• CRYSTAL-STRUCTURE

In the title dinuclear complex, [Ni-2(C8H7O2)(4)(C12H8N2)(2)-(H2O)], 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 mu(2)-bridging aqua ligand. The dimeric complex is located on a crystal-lographic 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 center dot center dot center dot O and pi-pi 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) angstrom, respectively].
