Abstract

The complexes [{HB(Me2pz)3}MoS(μ-S)2MoO(μ-OH)] 2 (1), [{HB(Me2Pz)3}MoO]2(μ-O)(μ-S2) (2) and {HB(Me2pz)3}MoS(μ-S)2MoS(S 2CNEt2) (3) have been isolated and characterized by X-ray crystallography 1·3C2H4Cl2 crystallizes in the triclinic space group C1 with a = 18.421 (3) Å, b = 10.547 (3) Å, c = 15.575 (4) Å, α = 90.07 (2)°, β = 104.76 (2)°, γ = 90.53 (2)°, and Z = 2. Each linear tetranuclear complex possesses 1 symmetry. 2·1/2C6H6 crystallizes in monoclinic space group P21/n with a = 15.126 (1) Å, b = 14.364 (2) Å, c = 20.145 (2) Å, β = 105.835 (7)°, and Z = 4. Complex 2 contains a rare mode of cis end-on disulfide bridge in which each molybdenum is coordinated to a different sulfur atom of the S22- ligand. 3·2/3CH2Cl2 crystallizes in the triclinic space group P1 with a = 12.103 (3) Å, b = 16.107 (4) Å, c =26.404 (7) Å, α = 79.82 (2)°, β = 82.00 (2)°, γ = 85.51 (2)°, and Z = 6. This binuclear complex contains both a six-coordinate molybdenum atom with an N3S3 coordination sphere and a five-coordinate molybdenum atom having only sulfur donor ligands. There are five different types of molybdenum-sulfur bonds in 3.
