Bis[N,N′-bis(diphenylmethylene)-ethylenediamine-κ2N, N′]copper(I) dichlorocuprate(I)

Abstract

The 1:1 adduct of N,N′-bis(diphenylmethylene)ethylenediamine (bz 2en) with copper(I) chloride, viz. [Cu(C28H 24N2)2]-[CuCl2], has been synthesized. The structure contains cationic moieties of CuI ions (Cu on a twofold axis) coordinated to four N atoms of two bz2en molecules (in a distorted tetrahedron) and linear dichlorocuprate(I) anions (with Cu on an inversion centre). These cations and anions are packed in columns along b. The packing of the cation and anion columns involves a significant C - H⋯Cl interaction and four short intermolecular C - H⋯π contacts, two of which are between cation columns.
