Ultrafine particles formed by XeCl laser photolysis of M(CO){sub 6}, M = V, Cr, Mo, and W, have been analyzed by Fourier transform mass spectrometry and other techniques. Novel metal carbide clusters, (MoC{sub 4}){sub n}, n = 1 {minus} 4 and (WC{sub 4}){sub m}, m = 1 {minus} 8, were detected and studied. The material produced by photolysis of V(CO){sub 6} shows a series of vanadium-oxygen clusters, V{sub x}O{sub 2x+2}, x = 2 {minus} 10. No clusters of any type were detected in the photolysis product of Cr(CO){sub 6}. Structures based on the experimental evidence are proposed and discussed in light of their chemical reactivity.
