Bis(ethylenediammonium) tris(pyridine-2,6-dicarboxylato-³O,O',N)cadmium(II) hexahydrate

A.-Y. Fu, D.-Q. Wang and A.-Z. Liu

Abstract: In the title complex, (C₂H₁₀N₂)₂[Cd(C₇H₃NO₄)₃]·6H₂O, the Cd^II atom is nine-coordinated by three pyridine-2,6-dicarboxylate ligands via six O atoms and three N atoms in a distorted tricapped trigonal prismatic structure. A crystallographic twofold rotation axis passes through the Cd atom and three atoms of one pyridine ring, viz. N, the C in the p-position and its attached H atom. The pyridine-2,6-dicarboxylate ligands, ethylenediammonium cations and uncoordinated water molecules contribute to the formation of intermolecular hydrogen bonds, forming a three-dimensional network.
