| Popis: | Reaction of MoIVO(S2PR2)2 with K{HB(Pripz)3} [HB(Pripz)3- = hydrotris(isopropylpyrazol-1-yl)borate] in refluxing toluene affords green L*MoIVO(S2PR2-S,S‘) complexes [L* = HB(3-Pripz)2(5-Pripz)- = hydrobis(3-isopropylpyrazol-1-yl)(5-isopropylpyrazol-1-yl)borate; R = Pri, Ph], which are converted upon reaction with boron sulfide in dichloromethane to the yellow thio analogues L*MoIVS(S2PR2-S,S‘). Crystals of L*MoIVO(S2PPri2) are monoclinic, space group P21/n, with a = 10.024(2) A, b = 20.999(9) A, c = 15.368(5) A, β = 100.57(2)°, V = 3180(2) A3, and Z = 4. Crystals of L*MoIVS(S2PPh2) are monoclinic, space group P21, with a = 10.801(8) A, b = 13.100(5) A, c = 12.023(9) A, β = 99.56(10)°, V = 1678(2) A3, and Z = 2. The mononuclear, distorted-octahedral complexes are isostructural and are composed of a terminal chalcogenide ligand [MoO = 1.671(3) A, MoS = 2.126(3) A], a bidentate dithiophosphinate-S,S‘ ligand, and a facial, tridentate L* ligand. In both cases the 5-isopropylpyrazole group is bound trans to the... |
