Özet
In the title Ni-II complex, [Ni(C10H11O2)(2)(C6H6N2O)(2)(H2O)2].2H(2)O, the divalent Ni ion occupies a crystallographically imposed centre of symmetry and is coordinated by two O atoms from the carboxylate groups of two 2,4,6trimethylbenzoate (TMB) ligands [Ni-O = 2.0438 (12) angstrom], two N atoms from the pyridyl groups of two isonicotinamide (INA) ligands [Ni-N = 2.1506 (15) angstrom] and two water molecules [Ni-O = 2.0438 (12) angstrom] in a slightly distorted octahedral geometry. The coordinating water molecules are hydrogen bonded to the non-coordinating carboxylate 0 atom of the TMB ligand [O center dot center dot center dot O) = 2.593 (3) angstrom], enclosing an S(6) hydrogen -bonding motif. Two solvent water molecules are also present in the formula unit. In the crystal, a network of intermolecular N-H center dot center dot center dot-O and O-H center dot center dot center dot-O hydrogen bonds link the complexes into a three-dimensional array. Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are from H center dot center dot center dot H (59.8%), O center dot center dot center dot H/H center dot center dot center dot O (20.2%) and C center dot center dot center dot H/H center dot center dot center dot C (13.7%) interactions.
