The carbonyls M(CO)6 (M=Cr, Mo, W) react with cis-(CH3)2AsC(CF3)=C(CF3)As(CH3)2 (L—L) to give the chelate derivatives (L—L)M(CO)4. These react with excess (L—L) on ultraviolet irradiation affording cis-(L—L)2M(CO)2 and trans-(L—L)2M(CO)2 and two isomers of fac-(L—L)2M(CO)3 where one (L—L) is acting as a monodentate ligand, and is either the cis ligand or its trans isomer.

Mode Of Coordination

The reactions of the potentially bidentate ditertiary arsine ligand bis-(diphenylarsino)methane, dam, with the hexacarbonyls of the Group VI transition metals have been investigated. N.m.r, spectroscopy has been used to determine the mode of coordination of the ligand. In the compounds M(CO)5(dam), M(CO)4(dam)2, and M(CO)3(dam)3 [M = Cr, Mo, W], dam is acting as a monodentate ligand, but in M(CO)4(dam) it is acting as a normal chelate coordinating to the metal through both arsenic atoms. In the cases of molybdenum and chromium, only, a further type of complex M(CO)2(dam) has been isolated. The results of N.M.R., infrared, and mass spectrometry, together with other physical measurements, can only be explained on the assumption that the ligand was coordinated to the metal by an arene π-linkage and by one arsenic atom. This novel structure has been confirmed by a single crystal X-ray diffraction study on the chromium compound.
