摘要

Four new quaternary transition metal arsenic chalcogenide Cs-TM-As-Q compounds (TM = Hg, Cd; Q = S, Se) were synthesized using different mixed solvents. A 1,4-diaminobutane(1,4-dab)/water mixed solvent system was used to solvothermally synthesize the selenoarsenates CsTMAsSe3(TM = Hg (1), Cd (2)). In1, the eight-membered ring anion chain consists of trigonal-planar [HgSe3] and trigonal-pyramid [AsSe3]. Compound2is similar to the eight-membered ring chain anion of compound1, and [CdAsSe3](-)further joins, through mu(3)-Se and Cd, to form the layer anions [CdAsSe3](-). A 2-diaminopropane (1,2-dap) and water mixed solvent system was used to synthesize two thioarsenates, Cs2TM2As2S6(TM = Cd (3), Hg (4)). Compounds3,4and2are isostructural; the Cd and Hg atoms are four coordinated. Compounds1-4utilize Cs(+)cations as a structural directing agent. Finally, the structural and optical properties of the novel series of arsenic chalcogenides were characterized.
