N2 - Three new mercury thioarsenates, (Me4N)[HgAsSe3], (Et4N) [HgAsSe3], and (Ph4P)2[Hg2As4Se11], with one-dimensional structures were synthesized hydrothermally from mixtures of HgCl2/3K3AsSe3/4(Me4NCl, Et4NBr, Ph4PBr), respectively, in sealed Pyrex tubes. The structures were determined by single-crystal X-ray diffraction analysis. (Me4N)[HgAsSe3] and (Et4N) [HgAsSe3] both crystallize in the monoclinic space group P21/n (No. 14) with a = 7.115(1) Å, b = 17.464(5) Å, c = 9.356(2) Å, β = 91.34(1)0, Z = 4, V = 1162.2(7) Å3 for the former and a = 7.175(2) Å, b = 18.907(4) Å, c = 10.897(3) Å, β = 99.56(2)0, Z = 4, V = 1457(1) Å3 for the latter. They have the same one-dimensional chain-like anionic framework with trigonal planar Hg2+ and [AsSe3]3- units. (Ph4P)2[Hg2As4Se11] crystallizes in the triclinic space group P-1 (No. 2) with a = 10.329(2) Å, b = 17.017(3) Å, c = 17.485(3) Å, α = 92.70(1)0, β = 105.73(1)0, γ = 103.71(1)0, Z = 2, V = 2853(1) Å3. [Hg2As4 Se11]2n-n also possess a one-dimensional chain-like structure consisting of both trigonal-planar and tetrahedral Hg2+ ions. It contains a unique [As4Se11]6- ligand which binds to four Hg2+ ions. The optical absorption and thermal properties of these compounds are reported.
