Abstract

The assembly reaction of 1,4-bis(1,2,4-triazol-1-yl)butane (btb) with different Cu(II) salts yields five coordination polymers: a 1D linear chain [Cu(btb)(HCOO)2(H2O)2]n (1), a 2D (4, 4) network [Cu(btb)2Cl2]n (2), a 3D cubic network [Cu(btb)(NCS)2]n (3), a threefold interpenetrating 3D diamondoid network {[Cu(btb)2(H2O)2](ClO4)2}n (4) and {[Cu(btb)2(H2O)2](NO3)2}n (5). 1 further constructs a 3D hydrogen bonding network. Two coordination polymers [Cu(btb)(1,2-bdc)]n (6) and {[Cu2(btb)(btec)(H2O)3]0.5H2O·CH3OH]n (7) were obtained with btb, 1,2-benzenedicarboxylate (1,2-bdc) and 1,2,4,5-benzenetetracarboxylate (btec). 6 is a 4-connected 65·8-CdS 3D coordination network. 7 is a (3,4,5)-connected pillared-layer 3D porous network where [Cu2(btb)(btec)(H2O)3] 2D layers are interlinked by btb pillars. The thermal stability of 1–7 was investigated. 3 and 6 are paramagnets with a negligible magnetic interaction while antiferromagnetic coupling between Cu(II) ions is observed in 7.
