Syntheses,Structures, and Magnetic Behavior of New Azide Linked Compounds with One‐ and Two‐Dimensional Structures

Three azide based compounds were synthesized employing aliphatic amines as site blocking agents: Ni(N₃)(C₆H₁₆N₂)₂]ClO₄ ( I ) C₆H₁₆N₂ = N,N′‐diethylethylenediamine (DEDA)], Cu₈(N₃)₁₆(C₆H₁₈N₄)₂] ( II ) C₆H₁₈N₄ = tris(2‐aminoethyl) amine (TREN)], and Cu₇(N₃)₁₄(C₇H₁₉N₃)₂] · 2H₂O ( III ) C₇H₁₉N₃ = 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 Cu₆ 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.
