A two dimensional coordination polymer, μ 1,3 benzenedi­carboxylato μ ethylenedi­aminezinc(II) trihydrate

Each dithiocarbamate ligand is in fact tridentate, chelating one Cd II atom as just described and simultaneously bridging another via the pyridyl-N atom so that the

Our group and that of Gao have already reported helical coordination polymers obtained through the reactions of silver salts and some unsymmetrical dipyridyl ligands such as

Amide derivatives of 2-hydroxyiminopropanoic acid have been widely used as versatile polynucleating ligands, in.. particular, for preparation of bi- and polynuclear complexes (Moroz

The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are

The coordination geometry of the Cd atom is distorted pentagonal bipyramidal. There are O—H O hydrogen bonds between the carboxyl O atoms, the aqua ligands and the

The 6-fluoronicotinate ligands are bound to the nickel(II) ion via their carboxylate O atoms in an O -monodentate fashion, whilst the 4,4 0 -bipyridine ligands act as bridge and,

A molecular drawing of compound 1 with complete coordination spheres of the metal atoms is shown in.. Figure 4 and selected geometrical parameters are presented in
