Reactivity of cyclopentadienyl molybdenum compounds towards formic acid: Structural characterization of CpMo(PMe 3)(CO) 2H, CpMo(PMe 3) 2(CO)H, [CpMo(μ-O)(μ-O 2CH)] 2, and [Cp*Mo(μ-O)(μ-O 2CH)] 2Here, the molecular structures of CpMo(PMe 3)(CO) 2H and CpMo(PMe 3) 2(CO)H have been determined by X-ray diffraction, thereby revealing four-legged piano-stool structures in which the hydride ligand is trans to CO. However, in view of the different nature of the four basal ligands, the geometries of CpMo(PMe 3)(CO) 2H and CpMo(PMe 3) 2(CO)H deviate from that of an idealized four-legged piano stool, such that the two ligands that are orthogonal to the trans H–Mo–CO moiety are displaced towards the hydride ligand. While CpRMo(PMe 3) 3–x(CO) xH (Cp R = Cp, Cp*; x = 1, 2, 3) are catalysts formore »
Tris(2-mercaptoimidazolyl)hydroborato Cadmium Thiolate Complexes, [Tm But ]CdSAr: Thiolate Exchange at Cadmium in a Sulfur-Rich Coordination EnvironmentA series of cadmium thiolate compounds that feature a sulfur-rich coordination environment, namely [Tm But]CdSAr, have been synthesized by the reactions of [Tm But]CdMe with ArSH (Ar = C 6H 4-4-F, C 6H 4-4-Bu t, C 6H 4-4-OMe, and C 6H 4-3-OMe). In addition, the pyridine-2-thiolate and pyridine-2-selenolate derivatives, [Tm But]CdSPy and [Tm But]CdSePy have been obtained via the respective reactions of [Tm But]CdMe with pyridine-2-thione and pyridine-2-selone. The molecular structures of [Tm But]CdSAr and [Tm But]CdEPy (E = S or Se) have been determined by X-ray diffraction and demonstrate that, in each case, the [CdS 4] motif is distortedmore »
