μ-Aqua-κ(2) O:O-di-μ-4-methyl­benzoato-κ(4) O:O′-bis­[(4-methyl­benzoato-κO)(1,10-phenanthroline-κ(2) N,N′)nickel(II)]

In the title dinuclear complex, [Ni(2)(C(8)H(7)O(2))(4)(C(12)H(8)N(2))(2)(H(2)O)], each Ni(II) atom is six-coordinated by three carboxylate O atoms from three 4-methyl­benzoate ligands, two N atoms from two 1,10-phenanthroline ligands, and one μ(2)-bridging aqua ligand. The dimeric complex is located on a crystallographic twofold axis and each Ni atom displays a distorted octa­hedral coordination geometry. The crystal structure is stabilized via intra­molecular hydrogen bonding of the bridging water mol­ecule and the uncoordinated carboxyl­ate O atoms, and by C—H⋯O and π–π stacking inter­actions [centroid–centroid distances between neighbouring phenanthroline ring systems and between the benzene ring of a 4-methyl­benzoate unit and a phenanthroline ring system are 3.662 (2) and 3.611 (3) Å, respectively].
