Two novel polymeric complexes, [Gd(HsTCAS)(H2O)7]·4H2O 1 and [Gd(HsTCAS) (CH3COCH3)(H2O)6]·6H2O 2 (H4TCAS = p-sulfonatothiacalix[4]arene), have been synthesized and characterized by single-crystal X-ray diffraction analyses. Complex 1 crystallizes in monoclinic, space group C2/m with a = 20.2308(12), b = 19.0894(10), c = 12.2448(7)A, β = 101.847(3)°, V = 4628.1(5)A^3, C24H43GdO27S8, Mr = 1169.25, Z = 4, Dc = 1.690 g/cm^3, F(000) = 2380,μ = 1.879 mm^-1, the final R = 0.0404 and wR = 0.1038 for 5127 observed reflections with I 〉 2σ(I). Complex 2 is pseudo-isostructural with complex 1. 相似文献

利用硝酸钴与配体5,5''-di (1H-1,2,4-triazol-1-yl)-(1,1''-biphenyl)-2,2''-dicarboxylic acid (H2DTBDA)进行溶剂热反应,制备了一个结构新颖的金属有机骨架{[Co (DTBDA)]2·DMF·MeOH}n (FJI-H37)。FJI-H37不仅具有适合气体分子吸附的0.69 nm的微孔,还具有良好的热稳定性及有机溶剂容忍性。气体吸附测试表明FJI-H37不仅能从C2H2/CO2(体积比50∶50)混合气中选择性吸附C2H2,还可以从CO2/N2(体积比15∶85)和CO2/CH4(体积比50∶50)混合气中选择性捕获CO2;固定床突破实验进一步证实了其高效的气体分离能力。 相似文献
