Abstract

Abstract A new three-dimensional heterometallic MnIICuII azide-bridged coordination polymer, [Mn2Cu(N3)6(en)2]n (1), was synthesized by assembling MnII, CuII, azide, and ethylenediamine in solution condition. The 3D structure of 1 can be described as end-on (EO) azide-bridged Mn2Cu trinuclear units linked by end-to-end (EE) azide bridges. Magnetic analysis of 1 indicates that the EO- and EE-azide bridges mediate the ferromagnetic and antiferromagnetic exchange interactions, respectively, with the antiferromagnetic coupling dominating the magnetic properties.
