title: (μ-Butane-1,2,3,4-tetra-carboxyl-ato)bis-[triaqua-(1,10-phenanthroline)nickel(II)] hexa-hydrate.
abstract: The asymmetric unit of the title compound, [Ni(2)(C(8)H(6)O(8))(C(12)H(8)N(2))(2)(H(2)O)(6)]·6H(2)O, contains a half of the centrosymmetric dinuclear complex mol-ecule and three uncoordinated water mol-ecules. In the dinuclear mol-ecule, two Ni(II) cations are bridged by the butane-1,2,3,4-tetra-carboxyl-ate (BTC(4-)) anion. Each Ni(II) atom is coordinated by two N atoms from the 1,10-phenanthroline ligand, one O atom from the BTC(4-) anion and three aqua ligands in a distorted octa-hedral geometry. Inter-molecuar O-H⋯O hydrogen bonds and π-π stacking inter-ations [centroid-centroid distances = 3.646 (2), 3.781 (2) and 3.642 (2) Å] consolidate the crystal packing.
