The title complex, (C 3 H 5 N 2 ) 2 [Co(C 7 H 3 NO 4 ) 2 (H 2 O) 2 ]Á4H 2 O, was prepared by a hydrothermal reaction. Each Co II atom is located on a crystallographic inversion centre and displays a distorted octahedral coordination geometry. The face-to-face distance of 3.529 (7) A ˚between partial

In the title polymer, [Cu(C 7 H 3 NO 4 )(H 2 O) 2 ] n , the Cu II ion is pentacoordinated and exhibits a distorted square-pyramidal environment formed by one N atom and two O atoms from pyridine-2,4-dicarboxylate ligands and two O atoms from coordinated water molecules. Each pyridine-2,4-dicarboxyla
The title centrosymmetric dinuclear complex, [Co 2 -(C 7 H 3 NO 4 ) 2 (C 10 H 8 N 2 )(H 2 O) 6 ]Á2H 2 O, has been synthesized hydrothermally. The cobalt(II) ion is coordinated in a slightly distorted octahedral environment by one N atom and one carboxylate O atom in N,O-chelating mode from one 2,4py
