Reactivity of Dithiocarbamates of Dimolybdenum. 3.1 Crystal and Molecular Structure of Oxobis[(diethylcarbamodithioato)(tetrahydrofuran)iodooxomolybdenum(V)]
The molybdenum (V) compound Mo2O3(dtc)2(THF)2I2 has been synthesized by iodine oxidation of Mo2(dtc)4, which is obtained from reaction of 4 equiv of sodium diethyldithiocarbamate trihydrate with 1 equiv of molybdenum acetate. The green Mo2(dtc)4 complex has the molybdenum acetate structure with four bridging dithiocarbamates. The molecular structure of the Mo(V) compound has been determined: The crystalline compound belongs to triclinic space group P1 with a = 8.055 (2) Å, b = 9.136 (3) Å, c = 11.551 (5) Å, α = 109.91 (2)°, β = 95.47 (2)°, and γ = 98.24 (2)°. The volume of the unit cell is 7.814 (6) Å3 with Z = 1. The structure was refined to RF = 4.33%. The complex exhibits a planar trans-O—Mo—O—Mo—O unit. In addition, the coordination sphere contains one THF per molybdenum, which exhibits an unusually long Mo-O(THF) bond.
