Mononuclear zinc(II), homodinuclear zinc(II) and heterodinuclear zinc(II)–copper(II) complexes derived from tris[(2-pyridyl)methyl]amine

Abstract

Mononuclear zinc(II), homodinuclear zinc(II) and heterodinuclear zinc(II)–copper(II) complexes derived from tris[(2-pyridyl)methyl]amine (L) have been prepared and characterised. The crystal structures of two mononuclear complexes, [ZnL(Cl)][BPh₄]·MeCN and [ZnL(O₂CPh)][BPh₄] show that the co-ordination geometries around the zinc are close to trigonal bipyramidal and that of the heterodinuclear complex [ZnCuL₂(p-O₂NC₆H₄ OPO₃][BPh₄]₂·H₂O shows that the metal atoms are separated by 5.86 Å and bridged by a phosphate monoester.
