摘要
合成了4个杂金属杯[4]配位聚合物{[Cd(L)(tpa)]·3H_2O}n(1),{[Zn_2(L)_2(tpa)_2]·3H_2O}n(2),{[Co(L)(oba)]·2DMA·0.5H_2O}_n(3)和{[Zn(L)(oba)]·DMA}n(4)(L=2-(1H-咪唑基-甲基)-6-(3-(1H-咪唑基-甲基)-5-叔丁基-2-羟基)苄基-4-叔丁基苯酚,H2tpa=对苯二甲酸,H2oba=4,4′-二苯醚二甲酸),并通过元素分析、热重、红外光谱、固态紫外、单晶X射线衍射和粉末X射线衍射对其进行了表征。单晶结构分析表明晶体1是单斜晶系,P21/n空间群,而晶体2,3和4均为三斜晶系,P1空间群。化合物1,2,3和4是由0维[M(N_4O_2C_(29)H_(36))](M=Zn,Co,Cd)的杂金属杯[4]与配体对苯二甲酸和4,4′-二苯醚二甲酸形成的一维配位聚合物。
Four metal hybrid calix[4]arene coordination polymers:{[Cd(L)(tpa)]·3H2O}n (1), {[Zn2(L)2(tpa)2]·3H2O}n (2), {[Co(L)(oba)]·2DMA·0.5H2O}n (3) and {[Zn(L)(oba)]·DMA}n (4) (L=2-((1H-imidazol-1-yl)methyl)-6-(3-((1H-imidazol-1-yl)methyl)-5-tert-butyl-2-hydroxybenzyl)-4-tert-butylphenol, H2tpa=terephthalic acid, H2oba=4,4'-oxy-bisbenzoic acid) have been successfully synthesized and characterized by elemental analysis, thermogravimetry, IR, the solid-sate UV-Vis spectra, single-crystal X-ray diffraction and PXRD. The single-crystal X-ray diffraction analysis reveals that complex 1 crystallizes in the monoclinic system, space group P21/n while complexes 2, 3 and 4 crystallize in the triclinic, space group P1. Complexes 1, 2, 3 and 4 are one-dimensional coordination polymers, which are formed through 0D[M(N4O2C29H36)] (M=Zn, Co, Cd) metal hybrid calix[4]arene bridged H2tpa and H2oba ligands.
