Abstract

Three novel metal polytellurides Rb4Hg5(Te2)2 (Te3)2Te3 (I), [Zn(en)3]4In16(Te2) 4(Te3)Te22 (II), and K2Cu2(Te2)(Te3) (III) have been prepared by solvothermal reactions in superheated ethylenediamine at 160 °C. Their crystal structures have been determined by single-crystal X-ray diffraction techniques. Crystal data for I: space group Pnma, a = 9.803(2) Å, b = 9.124(2) Å, c = 34.714(7) Å, Z = 4. Crystal data for II: space group C2/c, a = 36.814(7) Å, b = 16.908(3) Å, c = 25.302(5) Å, Β = 128.46(3)°, Z = 4. Crystal data for III: space group Cmcm, a = 11.386(2) Å, b = 7.756(2) Å, c = 11.985(2) Å, Z = 4. The crystal structure of I consists of 1D infinite ribbons of 1[Hg5(Te2) 2(Te3)2Te3]4-, which are composed of tetrahedral HgTe4 and trigonal HgTe3 units connected through the bridging Te2-, (Te2)2-, and (Te3)2- ligands. II is a layered compound containing InTe4 tetrahedra that share corners and edges via Te, Te2, and Te3 units to form a 2D slab that contains relatively large voids. The [Zn(en)3]2+ template cations are filled in these voids and between the slabs. The primary building blocks of III are CuTe4 tetrahedra that are linked by intralayer (Te3)2- and interlayer (Te2)2- units to form a 3D network with open channels that are occupied by the K+ cations. All three compounds are rare polytelluride products of solvothermal reactions that contain both Te2 and Te3 fragments with unusual metal-tellurium coordination.
