Crystal structure of cis-tetra-aqua-dichlorido-cobalt(II) sulfolane disolvate.

In the title compound, [CoCl2(H2O)4]·2C4H8SO2, the Co(II) cation is located on the twofold rotation axis and is coordinated by four water mol-ecules and two adjacent chloride ligands in a slightly distorted octa-hedral coordination environment. The cisoid angles are in the range 83.27 (5)-99.66 (2)°. The three transoid angles deviate significantly from the ideal linear angle. The crystal packing can be described as a linear arrangement of complex units along c formed by bifurcated O-H⋯Cl hydrogen bonds between two water mol-ecules from one complex unit towards one chloride ligand of the neighbouring complex. Two solvent mol-ecules per complex are attached to this infinite chain via O-H⋯O hydrogen bonds in which water mol-ecules act as the hydrogen-bond donor and sulfolane O atoms as the hydrogen-bond acceptor sites.

Crystal structure of 3-carbamo-thio-yl-pyridinium thio-cyanate.

In the cation of the title salt, C6H7N2S(+)·SCN(-), the C=S bond is oriented trans with respect to the C-C=N fragment in the pyridine ring. The planes of the aromatic ring and the thio-amide fragment of the cation make a dihedral angle of 38.31 (4)°. In the crystal, the components are linked by N-H⋯S and N-H⋯N, hydrogen bonds, forming a two-dimensional network parallel to (10-1).

catena-Poly[[trans-bis-(1,3-benzo-thia-zole-κN)manganese(II)]-di-µ-chlorido].

In the title coordination polymer, [MnCl2(C7H5NS)2] n , the Mn(II) ion is located on the inter-section of a twofold rotation axis and a mirror plane and adopts an octa-hedral coordination geometry defined by two mutually trans N atoms from benzo-thia-zole ligands which occupy the axial positions, and four Cl atoms which form the equatorial sites. The Mn(II) ions are connected by two bridging Cl atoms, forming chains parallel to the c axis. The crystal packing can be descibed as alternating layers parallel to (001) featuring π-π stacking inter-actions with a centroid-centroid distance of 3.6029 (15) Å.

2,2'-(Disulfanedi-yl)dianilinium dichloride dihydrate.

In the title hydrated mol-ecular salt, C12H14N2S2 (2+)·2Cl(-)·2H2O, the dihedral angle between the benzene rings in the dication is 9.03 (17)° and the C-S-S-C torsion angle is 96.8 (2)°. The crystal packing can be described as alternating organic and anionic water layers lying parallel to (100), which are linked by N-H⋯Cl and N-H⋯O hydrogen bonds. O-H⋯Cl hydrogen bonds and aromatic π-π stacking inter-actions [centroid-centroid separation = 3.730 (3) Å] are also observed.
