A one-dimensional (1D) copper(II) complex [Cu3(μ1,1-N3)6(dmp)2]n (1) has been synthesized and structurally characterized. The molecular structure of 1 is constructed by trimeric [Cu3(μ1,1-N3)6(dmp)2] units formed through two double symmetric (basal-to-basal) end-on (EO) azide bridges and the trimeric units are connected further by double asymmetric (basal-to-apical) EO azide bridges, giving 1D chain-like structure. The chains of 1 are linked together by N–H⋯Nazide hydrogen bonds and very weak Cu⋯Nazide coordination interactions from μ-1,1,3,3-N3 fashion to form two-dimensional (2D) supramolecular architecture. The magnetic structure can be considered as uniform 1D chain formed by linear trimeric CuII–CuII–CuII units and the dominating magnetic coupling occurs within the trimeric Cu3II unit. The magnetic study shows that the compound exhibits ferromagnetic interactions with Jt = + 8.36(2) cm−1 and Jc = + 0.35(4) cm−1 for intratrimeric and intertrimeric Cu3II unit based on 1D magnetic model, respectively.
