Tetra-?(3)-methano-lato-tetra-kis-[(2-formyl-6-meth-oxy-phenolato)methano-lnickel(II)].

ABSTRACT: The molecule of the title compound, [Ni(4)(CH(3)O)(4)(C(8)H(7)O(3))(4)(CH(3)OH)(4)], has S(4) symmetry. Each of the four Ni(II) atoms occupies every other corner of a cube, with the alternate corners occupied by ?(3)-methano-late bridging groups linking to three Ni(II) atoms. Each Ni(II) atom is in an O(6) octa-hedral coordination environment formed by three O atoms from three ?(3)-methano-late groups, one from methanol, and two others from a bidentate 2-formyl-6-meth-oxy-phenolate 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 inter-actions between the coordinated methanol OH groups and both the phenolic and meth-oxy O atoms of an adjoining 2-formyl-6-meth-oxy-phenolate moiety. In addition, there are weak inter-molecular C-H?O inter-actions involving the meth-oxy O atoms.
