Diiodido[4'-(4-pyrid-yl)-2,2':6',2''-terpyridine-κN,N',N'']copper(II).

ABSTRACT: The Cu(II) atom in the title compound, [CuI(2)(C(20)H(14)N(4))], has a distorted square-pyramidal coordination formed by the N atoms of the tridentate 4'-(4-pyrid-yl)-2,2':6'2''-terpyridine (pyterpy) ligand and two I atoms; one of the I atoms is in the apical position. In contrast to other known square-pyramidal diiodido- and dibromidocopper complexes of the pyterpy ligand in which metal-halogen distances are significantly different, in the title compound the apical and equatorial Cu-I bonds are almost identical [2.6141 (8) and 2.6025 (8) Å, respectively].
