Abstract

Three new copper azide compounds, Cu-5(N-3)(10)-( N-2AE-1,3-DAP)(2)] (I), Cu-5(N-3)(10)(N-3AP-1,3-DAP)(2)] (II), and Cu-7(N-3)(16)(1-(2-AE)PIP-H)(2)] (III) {where N-2AE-1,3-DAP = N-2-aminoethyl- 1,3-propanediamine, N-3AP-1,3-DAP = N-3-amino-propyl- 1,3-propanediamine, and 1-(2-AE) PIP = 1-(2-amino-ethyl) piperazine} have been prepared by employing aliphatic amine molecules as coordination blocking amines. All the structures are built up by copper azide units linked through a copper-amine metalloligand, forming two-dimensional layers. Compounds I and II have linear copper azide chains, whereas compound III has Cu-5 linear units. The structures of I and II are identical except for the blocking amine molecule. The blocking amine molecule in III is protonated, which is rarely observed. Magnetic studies indicate antiferromagnetic behavior with possible metamagnet-like features in all the compounds.
