Syntheses and properties of selenido mercurates with [HgSe2]2− anions in diverse chemical environments

Abstract

By aminothermal treatment of ternary CsxHgySez phases, or of Cs2Se with HgSO4, respectively, in 1,2-diaminoethane (en) and en/water mixtures at 150 °C, four new cesium selenido mercurate compounds Cs2[HgSe2] (1), [Cs2(H2O)2][HgSe2] (2), Cs[Cs3(H2O)0.5][HgSe2](Se2) (3) and Cs19(Hen)(H2en)(Se2)[HgSe2]2[HgSe3][Hg2Se5]2 (4) were synthesized. The precursor phases were prepared by fusion of Cs2Se and HgSe at 600 °C. 2 comprises an unprecedented 1D anionic selenido mercurate substructure. 3 and 4 are rare examples of mercurate compounds with different anions, one of which comprises a new type of a dinuclear chalcogenido mercurate anion. The structures of all four compounds were identified by single crystal X-ray diffraction. Micro X-ray fluorescence spectroscopy (μ-XFS) was used to confirm the heavy atom compositions, and optical absorption measurements were performed to determine the optical band gaps.
