Solvothermal Synthesis and Characterization of (NH_3 CH_2 CH_2 NH_3) HgSnS_4 with a Column Structure

摘要

A compound (NH_3CH_2CH_2NH_3)HgSnS_4 with a column structure was synthesized solvothermally and characterized by X-ray single-crystal diffraction. This compound crystallizes in the monoclinic space group C2/c with a = 1.3863(6) nm, 6=0.6640(3) nm, c=2.3198(10) nm, β =106. 168(7)° and Z = 8. It consists of anionic columns of [ HgSnS_4 ]_∞~(2-) that are interrupted by cationic columns of [ EnH_2 ]~(2+) . Its thermal and optical properties were studied.
