Abstract:	Metallocene dichlorides (RCp)₂MCl₂ (M = Zr, Hf; R = H, t-Bu) react with E/2HLiBEt₃ (E = S, Se) to give the symmetrical dinuclear compounds [(RCp)₂M(μ-E)]₂. UV irradiation in toluene of [(t-BuCp)₂Zr(CH₃)]₂(μ-O) in the presence of powdered sulfur or gray selenium gives the new compounds [(t-BuCp)₂Zr₂](μ-O)(μ-E).
