ABSTRACT

The asymmetric unit of the title organic-inorganic hybrid complex [systematic name: ethane-1,2-diaminium hexa-chlorido-stannate(IV)-4-meth-oxy-benz-alde-hyde (1/2)], (C2H10N2)[SnCl6]·2C8H8O2, contains one half of an ethyl-enedi-ammonium cation, one half of an [SnCl6]2- anion and one p-anisaldehyde mol-ecule. Both the organic cation and the quasi-regular octa-hedral inorganic anion are located about inversion centres. The organic cations and [SnCl6]2- anions lie in layers parallel to the ac plane with p-anisaldehyde mol-ecules occupying the space between the layers. A network of classical N-H⋯Cl and N-H⋯O hydrogen bonds exists between the ethyl-enedi-ammonium cations and the [SnCl6]2- anions and p-anisaldehyde mol-ecules. These inter-actions, together with non-classical C-H⋯O inter-actions between the ethyl-enedi-ammonium cations and the p-anisaldehyde mol-ecules, serve to hold the structure together. The crystal studied was refined as a two-component twin.

ABSTRACT

The crystal structure of the title salt adduct, 2C6H14N(+)·C4H4O4 (2-)·C4H6O4, consists of two cyclo-hexyl-ammonium cations, one succcinate dianion and one neutral succinic acid mol-ecule. Succinate dianions and succinic acid mol-ecules are self-assembled head-to-tail through O-H⋯O hydrogen bonds and adopt a syn-syn configuration, leading to a strand-like arrangement along [101]. The cyclo-hexyl-ammonium cations have a chair conformation and act as multidentate hydrogen-bond donors linking adjacent strands through inter-molecular N-H⋯O inter-actions to both the succinate and the succinic acid components. This results in two-dimensional supra-molecular layered structures lying parallel to (010).

ABSTRACT

Reaction of oxalic acid and di-phenyl-tin dichloride in the presence of cyclo-hexyl-amine led to the formation of the title salt, (C6H14N)2[Sn(C6H5)2(C2O4)2]. The dianion is made up from an Sn(C6H5)2 moiety cis-coordinated by two chelating oxalate anions, leading to an overall distorted octa-hedral coordination geometry of the Sn(IV) atom. The negative charges are compensated by two surrounding cyclo-hexyl-ammonium cations adopting chair conformations each. In the crystal, anions and cations are linked via a network of N-H⋯O hydrogen bonds into a layered arrangement parallel to (101).

ABSTRACT

The title compound, (C6H14N)2[Sn(C6H5)2Cl4], contains cyclo-hexyl-ammonium cations in general positions and a stannate(IV) anion that is located on a twofold rotation axis. The Sn(IV) atom in the complex anion is surrounded by four Cl(-) ligands and two trans-phenyl groups in a distorted octa-hedral configuration. The anions are connected with the cations through N-H⋯Cl hydrogen bonds. Every cation is involved in three N-H⋯Cl bonds to the chloride ligands of three different anions, and each chloride ligand is linked to two cations. This arrangement leads to a layered structure parallel to (010).

ABSTRACT

The title salt, (C6H14N)2[Sn(C2O4)Cl4], was obtained as a by-product from the reaction between 2C6H14N(+)·C2O4 (2-)·1.5H2O and SnCl2·2H2O. The cyclo-hexyl-ammonium cation has a chair conformation. The complex anion consists of an oxalate anion chelating the SnCl4 moiety, resulting in a distorted octa-hedral coordination sphere of the Sn(IV) atom with the O atoms in equatorial cis positions. In the crystal, cations and anions are linked through N-H⋯O and N-H⋯Cl inter-actions into a layered arrangement parallel to (100).

ABSTRACT

The central Sn(IV) atom of the penta-nuclear title complex, {[Sn(CH(3))(3)](3)O(2)C(CH(2))PO(3)[Sn(CH(3))(3)(H(2)O)](2)HO(2)C(CH(2))PO(3)}, is located on a twofold rotation axis; due to symmetry, the H atom of the carboxyl group of the anion is disordered with a site occupancy of 0.5. The central Sn(IV) atom is bonded to three methyl groups (one of which is disordered about the twofold rotation axis) and is symmetrically trans coordinated by two phospho-nate groups with Sn-O = 2.2665 (12) Šwhile the other SnMe(3) residues are asymmetrically trans coordinated with Sn-O = 2.1587 (12) and 2.3756 (13) Šfor one residue and Sn-O = 2.1522 (12) and 2.4335 (12) Šfor the other; the Sn-O distances involving two O atoms trans to carboxyl-ate are longer than those trans to phospho-nate groups. The Sn-C distances lie in a very narrow range [2.112 (2)-2.133 (3) Å]. The oxyanion behaves as a tetra-coordinating ligand. The bridging mode of the latter leads to the formation of layers parallel to (001) that are inter-connected by O-H⋯O and C-H⋯O hydrogen bonds.

ABSTRACT

The crystal structure of the title compound, (C6H14N)3[Sn(C2O4)2Cl2]Cl·H2O, contains three cyclo-hexyl-ammonium cations, one stannate(IV) dianion, one isolated chloride anion and one lattice water mol-ecule. The cyclo-hexyl-ammonium cations adopt chair conformations. In the complex anion, two bidentate oxalate ligands and two chloride anions in cis positions coordinate octa-hedrally to the central Sn(IV) atom. The cohesion of the mol-ecular entities is ensured by the formation of N-H⋯O, O-H⋯O, O-H⋯Cl and N-H⋯Cl inter-actions involving cations, anions and the lattice water mol-ecule, giving rise to a layer-like arrangement parallel to (010).

ABSTRACT

The structure of the title compound, (C(14)H(16)N)(2)[HgCl(2)(SO(4))], consists of an infinite chain propagating along the c direction, containing Hg(II) ions tetra-coordinated by two bridging O atoms of bis-monodentate sulfate anions and two chloride ligands. In the the crystal, N-H⋯O hydrogen bonding between the cations and the anionic chains consolidates the packing. The crystal structure was determined from an inversion twin with approximately equal twin domains.

ABSTRACT

Single crystals of the title salt, (C(3)H(10)N(3))(2)[Sn(CH(3))(2)(H(2)O)(4)](SO(4))(2), formed concomitantly with the already known [Sn(CH(3))(3)](2)SO(4)·2H(2)O. In the title structure, the Sn(IV) atom displays a slightly distorted octa-hedral coordination geometry defined by four O water atoms in the equatorial positions and two methyl groups in the axial positions. In the crystal, various O-H⋯O and N-H⋯O hydrogen-bonding inter-actions between the organic cation and the coordinated water mol-ecules as donors and the sulfate O atoms as acceptors result in a three-dimensional structure. The Sn(IV) atom is located on an inversion centre, resulting in half of the complex metal cation being in the asymmetric unit.

ABSTRACT

In the title compound, [Sn(2)(C(4)H(9))(4)(C(6)H(6)PO(3))(4)](n), the basic unit is a dimer containing two symmetry-related Sn(IV) atoms bridged by two hydrogenphenylphosphonate anions. This fragment is located about an inversion center, and each Sn(IV) atom is linked to two other hydrogenphenylphosphonate anions, giving a layered structure parallel to (010). The coordination geometry for the Sn(IV) atoms is close to octa-hedral. The layers are connected via O-H⋯O hydrogen bonds, generating a three-dimensional network. One butyl group is disordered over two sets of sites, with occupancies of 0.49 (2) and 0.51 (2).

ABSTRACT

In the title salt, [(CH(3))(2)CH](2)NH(2)](+)·[C(6)H(5)PO(2)(OH)](-), the anions are linked by pairs of O-H⋯O hydrogen bonds, forming inversion dimers. These dimers are bridged by the cations via N-H⋯O hydrogen bonds, leading to a three-dimensional structure.
