The diphosphine Ph2PCH2PPh2 (dppm) reacts with (bipy = 2,2'-bipyridine) or (phen = 1,10-phenanthroline) to give the seven-co-ordinate complexes (1a) and (1b) respectively.Sunlight irradiation of (1a) in dichloromethane solution leads to the mixed bidentate monocarbonyl complex (2) which has been characterized by X-ray crystallography.Crystals are orthorhombic, space group Pbca, with a = 18.440(7), b = 19.997(6), c = 17.900(9) Angstroem, and Z = 8.The structure has been refined to R = 0.072 and R' = 0.059 from 2078 reflections with F > 3?(F).The Mo co-ordination sphere is a distorted pentagonal bipyramid with carbonyl and one bipyridine nitrogen atom in the axial positions.Compound (2) reacts with ligands L, giving cationic species + and 2+ when L = P(OCH2)3CCH3.
