A new magnetic MOF with cyclic triazolate and linear azido mediators, [Co2(trz)3(N3)]n 1(trz- = 1,2,4-triazolate), was hydrothermally synthesized and structurally and magnetically characterized. 1 crystallizes in the rhombohedral P63/mmc space group with a = b = 10.0716(17), c = 7.5860(14) , V = 666.4(2) 3, Dc = 1.814 g/cm3, Mr = 364.09, Z = 2, F(000) = 360, μ = 2.499 mm1, the final R = 0.0676 and wR = 0.1952 for 229 observed reflections with I 2σ(I). Complex 1 consists of linear {Co(trz)3}n chains passing through a C6 rotation axis, which are interconnected with tetrahedral CoⅡ ion by u3-trz- ligands into a hexagonal three-dimensional antiferromagnetic framework. 相似文献
