Crystal structures of di-μ-chlorido-bis-({(E)-5-(ethyl-amino)-4-methyl-2-[(pyridin-2-yl)diazen-yl]phen-o-lato}copper(II)) and chlorido-bis-(1,10-phen-anthroline)copper(II) chloride tetra-hydrate.

ABSTRACT: The dark-red title complex crystallized from an equimolar methanol solution of (E)-5-(ethyl-amino)-4-methyl-2-[(pyridin-2-yl)diazen-yl]phenol and CuCl₂(phen) (phen = 1,10-phenanthroline) as a centrosymmetric dimer, [CuCl(C₁₄H₁₅N₄O)]₂. The Cu atoms are bridged by two Cl ligands and have a slightly distorted square-pyramidal coordination, where two N atoms from the azo and the pyridine moieties, a phenolic O and a Cl atom comprise the base and the other Cl occupies the apex position. The apical Cu-Cl bond, 2.6192 (4) Å, is longer than the basal one, 2.2985 (3) Å, due to Jahn-Teller distortion. The dimers are associated via weak inter-molecular hydrogen bonds and π-π stacking inter-actions between phenyl and pyridine rings.
