Multiple Bonds Between Main Group Elements and Transition Metals, XXV. Synthesis and Reactivity of Se1‐ and Se2‐Bridges in Organochromium Compounds Reaction of the ionic complex K[(η5‐C5Me5)Cr(CO)3] (1) with selenium(I) with selenium(I) chloride, Se2Cl2, yields the diselenium compounds 2 of composition (η5‐C5Me5)Cr(CO)5Se2 which is converted to the Se1 derivative (μ‐Se)[η5‐C5Me5)Cr2(CO)2]2 (3) with triphenylphosphane. 3 exhibits a linear, multiple bonded CrSeCr core structure. Reaction of 2 with diazomethane gives the novel mononuclear, paramagnetic selenoformaldehyde complex (η5‐C5Me5)‐Cr(CO)2(SeCH2) (4).
