reacts with two equivalents of Ph2PCH2CH2SH in tetrahydrofuran to give .An excess of tridentate PhP(CH2CH2SH)2 reacts with to yield > containing a pendant unco-ordinated SH group.This complex reacts reversibly with CO to form (CO)> -1>.The MIV complexes 2>.An X-ray crystal-structure determination for the complex with M = Mo shoved a distorted octahedral structure with an average Mo-S distance of 2.44 Aengstroem.The complex crystallises in the triclinic space group P, with a = 10.61(7), b = 10.867(4), c = 12.347(1) Angstroem, α = 85.06(4), γ = 63.0(4) deg, and Z = 2. 1337 Unique reflections with I0 >= 3?(I0) used in the solution converged at R = 0.0979.The hydrazido(2-) complexes Cl react with PhP(CH2CH2SH)2 in MeOH to give 2> (M = Mo or W).An X-ray crystal-structure determination of the complex with M = Mo revealed a distorted pentagonal-bipyramidal structure with a linear apical NNMe2 ligand.The complex crystallises in the monoclinic space group P21/n, with a = 11.349(2), b = 12.403(3), c = 19.302(4) Angstroem, β = 104.28(2) deg, and Z = 4. 2796 Unique reflections with I0 > 3?(I0) used in the solution converged at R = 0.605.
