Structural characterization of Cu(bpma)(2)center dot[BF4](2), (bpma : N-{[3-(dimethoxyniethyl)phenyl]imethylidene}[di-(2-pyridyl)]methanamine)

Abstract

The crystal and molecular structure of a copper complex formulated as Cu(bpma)(2)(.)[BF4](2), (bpma: N-{[3-(dimethoxymethyl)phenyl]methylidene}[di-(2-pyridyl)]methanamine) is reported. The ligand results from the reaction of the unmodified carboxaldehyde group of 1,3-benzene-dicarboxaldehyde with the solvent, methanol, giving the acetal. The structure is monomeric and contains the copper cation at a center of symmetry, octahedrally coordinated to two tridentate, symmetry-related bpma ligands. The charge balance is achieved through the inclusion in the structure of (highly disordered) BF4- counter ions.
