Abstract

New bioinorganic complexes of the aspartic acid with the antimony or bismuth triiodide were synthesized by a direct solid-solid reaction at room temperature. The formula of the complex is MI(3)OOCCH(2)CH(NH(2))CO x 2.5H(2)O (M = Sb, Bi). The complex may be a dimer with bridge structure. The crystal structure of the complexes belongs to a triclinic system. The lattice parameters are a = 0.9883 nm, b = 1.4284 nm, c = 2.0114 nm, alpha = 94.46 degrees , beta = 99.76 degrees and gamma = 100.1 degrees for the complex of antimony and a = 0.9756 nm, b = 1.4560 nm, c = 1.9875 nm, alpha = 94.18 degrees , beta = 97.25 degrees and gamma = 101.16 degrees for the complex of bismuth. The infrared spectra and thermal analyses can demonstrate the complex formation between the aspartic acid and the antimony or bismuth ion.

摘要

通过在室温下直接进行固-固反应，合成了天冬氨酸与三碘化锑或三碘化铋的新型生物无机配合物。配合物的化学式为MI(3)OOCCH(2)CH(NH(2))CO×2.5H(2)O（M = Sb，Bi）。该配合物可能是具有桥连结构的二聚体。配合物的晶体结构属于三斜晶系。对于锑配合物，晶格参数为a = 0.9883 nm，b = 1.4284 nm，c = 2.0114 nm，α = 94.46°，β = 99.76°，γ = 100.1°；对于铋配合物，晶格参数为a = 0.9756 nm，b = 1.4560 nm，c = 1.9875 nm，α = 94.18°，β = 97.25°，γ = 101.16°。红外光谱和热分析可以证明天冬氨酸与锑或铋离子之间形成了配合物。
