The molecular structure of the neutral mononuclear title complex, [Ni(C17H12ClN2O2)2(CH3OH)2], is centrosymmetric. The NiII atom, which is located on an inversion center, is in a distorted octahedral coordination, defined by four O atoms from two ligands as well as two O atoms from two methanol molecules. Intermolecular O-HN hydrogen bonds between the hydroxy group of methanol and a pyrazole N atom link the molecules, forming a two-dimensional network parallel to (100).
