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 CsTMAsSe _(3) (TM = Hg ( 1 ), Cd ( 2 )). In 1 , the eight-membered ring anion chain consists of trigonal-planar [HgSe _(3) ] and trigonal-pyramid [AsSe _(3) ]. Compound 2 is similar to the eight-membered ring chain anion of compound 1 , and [CdAsSe _(3) ] ~(?) further joins, through μ _(3) -Se and Cd, to form the layer anions [CdAsSe _(3) ] ~(?) . A 2-diaminopropane (1,2-dap) and water mixed solvent system was used to synthesize two thioarsenates, Cs _(2) TM _(2) As _(2) S _(6) (TM = Cd ( 3 ), Hg ( 4 )). Compounds 3 , 4 and 2 are isostructural; the Cd and Hg atoms are four coordinated. Compounds 1–4 utilize Cs ~(+) cations as a structural directing agent. Finally, the structural and optical properties of the novel series of arsenic chalcogenides were characterized.
