Abstract

(S 4 N 3 ) 2 Se 2 Cl 10 , (S 4 N 3 ) 2 Se 2 Cl 6 and [(S 4 N 3 )SeCl 5 ] n are formed by the reaction of S 4 N 4 , Se 2 Cl 2 , and SOCl 2 . The structures of the three compounds where determined by X-ray diffraction. The yellow crystals of (S 4 N 3 ) 2 Se 2 Cl, 10 are monoclinic, space group P2 1 /a, a = 817.5(2) pm, b = 1790.4(5) pm, c = 843.1(6) pm, β = 104.31(4)°, Z = 2. The Se 2 Cl, 10 2- anion consists of 2 Cl-bridged distorted octahedra. (S 4 N 3 ) 2 Se 2 Cl 6 forms red monoclinic crystals, space group P2 1 /c, a = 1036.5(3) pm, b = 1376.5(5) pm, c = 1400.4(4) pm, β = 100.65(2)°, Ζ = 4. In the Se 2 Cl 6 2- anion the Se atoms have a square planar environment. The yellow crystals of (S 4 N 3 )SeCl 5 are orthorhombic, space group P2 1 2 1 2 1 , a = 734.2(3) pm, b = 989.4(4) pm, c = 1627.4(6) pm, Z = 4. In the SeCl 5 - anion the Se atom has an octahedral environment of chlorine atoms, thus forming a polymeric structure.
