Matrix isolation evidence for a primary CO dissociation pathway in the photochemistry of the metal-metal bonded dimers (h5-C5H5)2M2(CO)6 (M = Mo, W): Matrix isolation evidence for a primary CO dissociation pathway in the photochemistry of the metal-metal bonded dimers (h5-C5H5)2M2(CO)6 (M = Mo, W).Some chemicals with cas registry numbers like 88428-56-2 and 12091-64-4 are also used.

DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Photolysis of the metal-metal bonded dimers Cp2M2(CO)6 (M = Mo, W; Cp = h5-cyclopentadienyl) in PVC-film (12-77 K) and frozen-gas (12 K) matrixes gives the novel dimers Cp2M2(CO)5, which have a structure suggested (on the basis of IR spectroscopy) to contain a 4-electron-donor, bridging CO ligand and 2 semi-bridging CO ligands. .

DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 75 [CpMo(CO)3]2 (Cp = C5H5) reacts with S2C2(CF3)2 in refluxing methylcyclohexane soln. to give Cp(CO)2Mo[m-S2C2(CF3)2]2MoCp (I). I loses its CO ligands on photolysis in soln. to give [CpMo(m-S2C2(CF3)2)]2 (II). I and II were characterized by 1H and 19F NMR spectroscopy, elemental anal., mass spectrometry, and x-ray diffraction techniques. Electrochem. properties of both compds. were also studied. I contains two asym. bridging S2C2(CF3)2 ligands, and both CO ligands are attached to the same Mo atom. The Mo-Mo distance suggests minimal Mo-Mo bonding. .
