Abstract The complexes [Et4N][(Ph3P)2{M′S2 MS2Fe}Cl2] (M=Mo,M′=Ag;M=W,M′=Cu, Ag) have been obtained by reaction of [Et4N]2[S2 MS2FeCl2] (M=Mo, W) with Cu(PPh3)3Cl or Ag(PPh3)3NO3 in MeCN/CH2Cl2, respectively. Crystal data for [Et4N][(PPh3)2 {AgS2MoS2Fe}Cl2] (I): triclinic, P $$\bar 1$$ (No. 2),Z=2,a=13.41(1)Å,b=15.54(1)Å,c=12.30(1)Å, α=105.24(6)°, β=94.63(7)°, γ=101.38(6)°, andV=2399(4)Å3. The bond lengths of Mo-Fe bond and the Mo-Ag distance are 2.756(2)Å and 3.033(2)Å, respectively. Crystal data for [Et4N][(PPh3)2 {AgS2WS2Fe}Cl2] (II): triclinic, P $$\bar 1$$ (No. 2),Z=2,a=13.457(5))Å,b=15.601(6)Å,c=12.338(4)Å, α=105.20(3)°, β=94.61(4)°, γ=101.43(4)°, andV=2426(2)Å3. The bond length of W-Fe bond and the W-Ag distance are 2.786(2)Å and 3.076(1)Å, respectively. Crystal data for [Et4N][(PPh3)2 {CuS2WS2Fe}Cl2] (III): triclinic, P $$\bar 1$$ (No. 2),Z=2,a=13.498(5)Å,b=15.372(4)Å,c=12.340(4)Å, α=105.54(2)°, β=93.32(3)°, γ=101.40(3)°, andV=2401(1)Å3. The bond lengths of W-Fe bond and the W-Cu bond are 2.800(1)Å and 2.851(1)Å, respectively.
