Diaquabis(4-methylbenzoato-κO)bis(nicotinamide-κN (1))nickel(II)
The title Ni(II) complex, [Ni(C(8)H(7)O(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], is centrosymmetric with the Ni atom located on an inversion center. The molecule contains two 4-methylbenzoate (PMB) and two nicotinamide (NA) ligands and two coordinated water molecules, all ligands being monodentate. T...

Sumario: | The title Ni(II) complex, [Ni(C(8)H(7)O(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], is centrosymmetric with the Ni atom located on an inversion center. The molecule contains two 4-methylbenzoate (PMB) and two nicotinamide (NA) ligands and two coordinated water molecules, all ligands being monodentate. The four O atoms in the equatorial plane around the Ni atom form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxylate group and the adjacent benzene ring is 26.15 (10)°, while the pyridine and benzene rings are oriented at a dihedral angle of 87.81 (4)°. In the crystal structure, intermolecular O—H⋯O and N—H⋯O hydrogen bonds link the molecules into a three-dimensional network. The π–π contact between the benzene rings [centroid–centroid distance = 3.896 (1) Å] may further stabilize the crystal structure. A weak C—H⋯π interaction involving the pyridine ring also occurs. |
