The crystal and molecular structures of (PPh4)2[(WS4)WS(WS4)] (1a) and CS2[(WS4)WO(WS4)H2O] · 2 H2O (2a), which contain the first reported isopoly-thioanion of a transition metal have been determined: 1a: (P1̅, a = 913.0(1), b = 1060.1(2), c = 1333.9(2) pm, α = 87.11(1), β = 85.18(1), γ = 83.07(1)°, V = 1277.6 · 106 pm3, Z = 1); 2a: (P21/n, a = 671.6(2), b = 2018.5(4), c = 714.4(2) pm, β = 101.42(2)°, V = 949,3 · 106 pm3, Z = 2) and compared with that of the trimetallic heteropoly-thioanion of(AsPh4)2[(WS4)Ni(WS4)] (3a). 3a: (P1̄, a = 1255.2(3), b = 1277.1(3), c = 939.0(2) pm, α = 113.19(2), β = 96.28(2), γ = 108.72(2)°, V = 1261.5 · 106 pm3, Z = 1). Though there are delocalized orbitals in the isopoly-thioanions they can be regarded as coordination compounds of WIVX2+ containing two WVIS42- ligands.
