Three azide based compounds were synthesized employing aliphatic amines as site blocking agents: [Ni(N 3 )(C 6 H 16 N 2 ) 2 ]ClO 4 ( I ) [C 6 H 16 N 2 = N , N ′‐diethylethylenediamine (DEDA)], [Cu 8 (N 3 ) 16 (C 6 H 18 N 4 ) 2 ] ( II ) [C 6 H 18 N 4 = tris(2‐aminoethyl) amine (TREN)], and [Cu 7 (N 3 ) 14 (C 7 H 19 N 3 ) 2 ] · 2H 2 O ( III ) [C 7 H 19 N 3 = 3,3′‐diamino‐ N ‐methyldipropylamine (DMDA)]. The compounds I and II have one‐dimensional structure and III has a two‐dimensional structure. Compound I is a simple linear cationic Ni–azide chain and compound II has Cu 6 azide units forming a column terminated by the copper‐metalloligand generated in‐situ during the course of the reaction. The charge compensation perchlorate anions occupy spaces in between the chains in I . Compound II packs in a herringbone arrangement, which is not commonly observed in low‐dimensional structures. Compound III has one‐dimensional copper‐azide chains connected through copper‐metalloligand forming the two‐dimensional structure. All the three compounds exhibit anti‐ferromagnetic behavior.
