title: Tetra-aqua-bis[3-(4-pyrid-yl)benzoato-κN]nickel(II).
abstract: The Ni(II) atom in the title compound, [Ni(C(12)H(8)NO(2))(2)(H(2)O)(4)], exists in an all-trans octa-hedral coordination environment. The 3-(4-pyrid-yl)benzoate ligand binds to Ni atom through the pyridyl N atom; the pyridine and benzene rings are oriented at a dihedral angle of 26.27 (10)°. Adjacent complexes are linked by O-H⋯O hydrogen bonds, forming a three-dimensional network. The metal atom lies on a special position of 2 site symmetry in the crystal structure.
