A one-dimensional (1D) copper(II) complex [Cu3(l1,1-N3)6(dmp)2]n (1) has been synthesized and structurally
characterized. The molecular structure of 1 is constructed by trimeric [Cu3(l1,1-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 l-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 CuII
3 unit. The magnetic
study shows that the compound exhibits ferromagnetic interactions with Jt = + 8.36(2) cm1 and Jc =
+ 0.35(4) cm1 for intratrimeric and intertrimeric CuII
3 unit based on 1D magnetic model, respectively.
