ABSTRACT
In the title compound, C(9)H(12)NO(6)P, intra-molecular C-Hâ¯O hydrogen bonds form five- and six-membered rings. In the crystal, inversion dimers lined by pairs of C-Hâ¯O hydrogen bonds occur with ring motifs R(2) (2)(10). The O atom of the hydr-oxy group behaves as an accepter and the benzene ring as donor. Adjacent dimers are connected through O-Hâ¯O links.
ABSTRACT
In the mol-ecule of the title compound, 2C(4)H(10)N(3)O(2) (+)·SO(4) (-), the cations are planar (r.m.s. deviations = 0.0144 and 0.0236â Å) and oriented at a dihedral angle of 62.30â (4)°. Intra-molecular N-Hâ¯O hydrogen bonds result in the formation of two planar six-membered rings. The cations are linked to the sulfate ion through inter-molecular C-Hâ¯O and N-Hâ¯O hydrogen bonds, forming an R(2) (2)(8) ring motif. In the crystal structure, inter-molecular N-Hâ¯O and C-Hâ¯O hydrogen bonds link the mol-ecules into a three-dimensional network.
ABSTRACT
The title compound is a double oxygen-bridged dimeric heteronuclear metal complex. The coordination around the Cu atom is distorted square-planar involving two O and two N atoms from the bis(salicylidene)-1,3-propanediamine ligand. The Zn atom in the molecule has a distorted tetrahedral coordination sphere consisting of the two O atoms of the ligand and the two Br atoms. The bridging plane between the metal atoms is not planar.
ABSTRACT
In the title compound, the coordination around the Cu atom is a distorted square-pyramid involving three N atoms from the ligand and one N atom from the azido group at the basal plane. The Cl atom is located at the apical position. The Cu atom is 0.32(5)A above the basal plane. There are three intramolecular and four weak intermolecular hydrogen bonds in the structure. IR spectra confirm the asymmetric N3 stretching vibrations of the terminal azide group.
