We have previously shown that terphenyl main group element halides (ArEX; E = Ge, Sn) react readily with charged transition metal carbonyl precursors (e.g. K[MCp(CO)2]) to furnish mixed main group metal-transition metal carbonyls (e.g. ArE-MCp(CO)2; E = Ge, Sn; M = Mo, W).1,2 This chemistry was limited by the availablility of suitable precursors with which to carry out the salt metathesis reactions. We now show that we can access similar clusters (e.g. (ArE)xMy(CO)z E = Ga, Ge, Sn; M = Mo, W, Cr, Co. Fe) by irradiating the neutral Group 13/14 dimetallene/dimetallyne in the presence of a neutral transition metal carbonyl starting material.    1. Pu, L.; Twamley, B.; Haubrich, S. T.; Olmstead, M.
