- Abstract
Three new copper azide compounds, [Cu5(N3)10-(N-2AE-1,3-DAP)2] (I), [Cu5(N3)10(N-3AP-1,3-DAP)2] (II), and [Cu7(N3)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 Cu5 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.
