Abstract

A new dicopper(II) complex [Cu₂(μ-C₂O₄)(bpy)₂(H₂O)₂(NO₃)₂] (1) has been synthesized and its structure determined (bpy = 2,2'-bipyridine). The structure consists of centrosymmetric [Cu₂(μ- C₂O₄)(bpy)₂(H₂O)₂(NO₃)₂] molecules with each Cu(II) ion in a distorted octahedral environment: two nitrogen atoms from bpy, two oxygen atoms from the oxalate ion in the basal plane and two oxygen atoms from H₂O and the nitrato group in the two axial positions. The unusual ligand arrangement in (1) and the packing of molecules are attributed to intermolecular and intramolecular hydrogen bonding. The intermolecular and intramolecular hydrogen bonding formed a hydrogen bond plane and the intermolecular hydrogen bonding gave rise to a zigzag chain structure. The e.p.r. study of the polycrystalline powder at 1l0 K gives g is perpendicular to = 2.04 and g is parallel with = 2.20, typical of axially elongated copper(II) systems, and the appearance of the half-field signals suggests a magnetic interaction between the two Cu(II) ions.
