X-Ray structure of Cu2(medpco)Cl4, a complex with the potentially binucleating N-oxide ligand N,N′-bis(2-N,N-dimethylaminoethyl) pyridine-2,6-dicarboxamide 1-oxide (medpco)

Abstract

The complex Cu₂(medpco)Cl₄, with the N-oxide ligand N,N′-bis (2-N,N′-dimethylaminoethyl)pyridine -2,6-dicarboxamide 1-oxide (medpco), does not have the expected binucleated structure; X-ray analysis shows that one Cu^II ion occupies an ONN ligand site, and is linked by a double chloride bridge to an external Cu^II ion whose co-ordination is completed by two terminal chlorides.
