Abstract

A new coordination polymer of Ni2+, (dicyanamide, herein denoted dca) and 2,9-dimethyl-1,10-phenanthroline (dmphen), has been synthesized, structurally and magnetically characterized. {[Ni2(dmphen)2[µ-dca]4} n (1), which crystallizes in the monoclinic space group P21 /n, has a 2-D network that consists of double-bridged [Ni2(dca)2(dmphen)2]2+ “dimers” connected via single-bridging dca ligands and exhibits a typical (6, 3) topological network. Each NiN6 octahedron comprises a bidentate dmphen and four µ1,5-bridging dca anions. Magnetic susceptibility measurements indicate antiferromagnetic interactions between Ni(II) ions via the dca bridge.
