摘要
One novel cobalt coordination polymer, {[Co（HTCB）（4,4＇btb）]＇HzO}n （1, H3TCB = 1,3,5-tris（4-carboxyphenyl）benzene, 4,4＇-btb = 4,4＇-bis（1,2,4-triazol-3-yl）biphenyl）, has been synthesized and characterized by elemental analysis, IR, powder X-ray diffraction （PXRD）, and thermogravimetric （TG） analyses. X-ray diffraction analysis reveals that complex 1 is a 2D 2-fold interpenetrated {44,62}-sql [Co（HTCB）（4,4＇-btb）] sheet based on the 1D [Co（HTCB）]n chains and 1D [Co（4,4＇-btb）]n chains. The crystal of 1 crystallizes in triclinic, space group P1 with a = 9.529（12）, b = 13.914（16）, c = 14.906（17） A, V= 1903（4） A3, Z = 2, C45H34N6CoO71 Mr= 829.71, Dc = 1.448 g/cm3, F（000） = 858 andμ（MoKa） = 0.514 mm-1. The final R = 0.0655 and wR = 0.1136 for 6603 observed reflections with 1 〉 2a（/） and R = 0.1136 and wR = 0.1747 for all data.
