Abstrakt: The organocyclotriarsane, CH3C(CH2As)3(1), reacts with chromium hexacarbonyl on ultraviolet irradiation to give the complex CH3C(CH2As)3Cr(CO)5(2), in which the cyclo-triarsane is behaving as a monodentate ligand. The crystal structure of 2 has been determinated by X-ray diffraction. The monoclinic unit cell (space group P21/n) contains 4 isolated molecules in a hexagonal closest packing. The mass spectrum of 2 shows the parent peak and clear fragmentation patterns. The infrared and Raman spectra are reported for 1 and 2 in the 3000-30 cm-1region. Most of the fundamental vibrations are assigned.
