Syntheses, Structures, and Properties of New Quaternary Gold-Chalcogenides: K2Au2Ge2S6, K2Au2Sn2Se6, and Cs2Au2SnS4

1998

The new compounds K2Au2Ge2S6 (1), K2Au2Sn2Se6 (2), and Cs2Au2SnS4 (3) have been synthesized through direct reaction of the elements with a molten polyalkalithiogermanate(stannate) flux at 650, 550, and 400 °C, respectively. Their crystal structures have been determined by single crystal X-ray diffraction techniques. 1 crystallizes in the monoclinic space group P21/n with a = 10.633(2) A, b = 11.127(2) A, c = 11.303(2) A, β = 115,37(3)°, V = 1208,2(3) A3 and Z = 4, final R(Rw) = 0.045(0.106). 2 crystallizes in the tetragonal space group P4/mcc with a = 8.251(1) A, c = 19.961(4) A, V = 1358,9(4) A3 and Z = 4, final R(Rw) = 0.040(0.076). 3 crystallizes in the orthorhombic space group Fddd with…
