Solid-State Synthesis, Characterization, And Biological Activity Of The Bioinorganic Complex Of Aspartic Acid And Arsenic Triiodide

The bioinorganic complex of aspartic acid and arsenic triiodide was synthesized by a solid-state reaction at room temperature. The formula of the complex is AsI3[HOOCCH2CH(NH2)COOH](2.5). The crystal structure of the complex belongs to monoclinic system with lattice parameters: a = 1.0019 nm, b = 1.5118 nm, c = 2.1971 nm, and beta = 100.28 degrees. The infrared spectra can demonstrate the complex formation between the arsenic ion and aspartic acid, and the complex may be a dimer with bridge structure. The result of primary biological test indicates that the complex possesses better biological activity for the HL-60 cells of the leukemia than arsenic triiodide.
