| Abstract: | The title compounds were prepared from the reation of (NH4)2MS4 (M=W,Mo),AgNO3,NadtcEt2 and Et4NBr in CH3CN-H2O solution. The isomorphous compounds [Bu4N]2[W2Ag3S8Et2du] ( I ) and [Bu4N]2[Mo2Ag3S8Et2dtc] (Ⅱ) crystallize in triclinic space qroup Pi with the following crystal parameters:α=13. 043(4),b = 21. 640(6),c=10. 757(6)A ,α=95. 09(5),β = 91. 90(4),γ = 98. 57(3)°,Z = 2,V = 2987A3,Dc=1. 76g/cm3 for I 5;a= 12. 989(2) ,b=21. 574 (9) ,c= 10. 7/1(1) A .α= 95. 06(7), β=91. 61(4), γ=98. 52(2)°, Z = 2,V = 2961 A3.Dc= 1. 58g/cm3 for Ⅱ . The final R and Rw values are 0. 061 and 0. 072 for Ⅰ ,and 0. 062 and 0. 076 for Ⅱ The M2Ag3 (M = W, Mo) unit in anion M2Ag3S8Et2dtc forms a five-membered ring. |
