title: Bis[μ-2-(2-carboxyl-atophen-yl)acetato]-κO,O:O;κO:O,O-bis-[aqua-(1,10-phenanthroline-κN,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 octa-hedral 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 mol-ecules and one of the O atoms of the carboxyl-atomethyl group.
