Bis[μ-2-(2-carboxylatophenyl)acetato]-κ³O¹,O^1′:O²;κ³O²:O¹,O^1′-bis[aqua(1,10-phenanthroline-κ²N,N′)nickel(II)]

Abstract

The title compound, [Ni 2 (C 9 H 6 O 4 ) 2 (C 12 H 8 N 2 ) 2 (H 2 O) 2 ], is isostructural with the Zn II analogue. Each Ni II atom is coordinated in a distorted octahedral geometry by three O atoms from two homophthalate anions, one aqua O atom and two 1,10-phenanthroline N atoms. The two Ni II atoms are linked by two bridging homophthalate dianions into a centrosymmetric dinuclear unit. The dinuclear units are linked into one-dimensional ladder-like chains along [100] by O—H...O hydrogen bonds between the coordinated water molecules and one of the O atoms of the carboxylatomethyl group.
