Abstract
The molecule of the title compound, [Ni4(CH3O)4(C8H7O3)4(CH3OH)4], has S 4 symmetry. Each of the four NiII atoms occupies every other corner of a cube, with the alternate corners occupied by μ3-methanolate bridging groups linking to three NiII atoms. Each NiII atom is in an O6 octahedral coordination environment formed by three O atoms from three μ3-methanolate groups, one from methanol, and two others from a bidentate 2-formyl-6-methoxyphenolate ligand. The Ni—O bond distances range from 2.0020 (14) to 2.0938 (14) Å, the cis bond angles range from 81.74 (6) to 97.63°, and the trans bond angles range from 168.76 (5) to 175.22 (6)°. There are bifurcated hydrogen-bonding interactions between the coordinated methanol OH groups and both the phenolic and methoxy O atoms of an adjoining 2-formyl-6-methoxyphenolate moiety. In addition, there are weak intermolecular C—H⋯O interactions involving the methoxy O atoms.
