[Ni(cyclam)(μ1,3-dca)2Cu(μ1,5-dca)2]:  A Genuine 3D Bimetallic Coordination Polymer Containing Both μ1,3- and μ1,5-Bidentate Dicyanamide Bridges and a Ferromagnetic Interaction between Copper(II) and Nickel(II) Ions

The structure of [Ni(cyclam)(μ1,3-dca)2Cu(μ 1,5-dca)2], a genuine 3D dicyanamide-bridged bimetallic coordination polymer, is made up of 2D [Cu(μ-1,5dca)2]n layers connected by [Ni(cyclam)(μ1,3-dca)2] bridging moieties; it exhibits a ferromagnetic exchange interaction between copper(II) and nickel(II) ions through the μ1,3-bidentate dicyanamide bridges.
