title: Aqua-bis(4-methyl-benzoato)-κO;κO,O'-bis-(pyridine-κN)nickel(II).
abstract: In the title mononuclear complex, [Ni(C(8)H(7)O(2))(2)(C(5)H(5)N)(2)(H(2)O)], the Ni(II) atom is in a distorted octa-hedral arrangement, coordinated by three carboxylate O atoms from one bidentate 4-methyl-benzoate ligand and one monodentate 4-methyl-benzoate ligand, two N atoms from pyridine ligands, axially positioned, and a water mol-ecule. The equatorially positioned water mol-ecule and uncoordinated carb-oxylate O atom form an intra-molecular hydrogen bond. An inter-molecular O-H⋯O hydrogen bond between the coordinated water mol-ecule and carboxylate O atom of the 4-methyl-benzoate ligand forms infinite chains along the b axis. These chains are connected by C-H⋯π inter-actions.
