N2 - The compound (μ-Se)[η5-C5H5)Fe(CO)2]2 (1) has labile metalselenium bonds and therefore undergoes insertion and metathesis reactions. Thus, reaction with elemental selenium gives the novel FeSeSeFe chain-type complex (μ,η1:η1-Se2)[(η5-C5H5)Fe(CO)2]2 (2). Both compounds 1 and 2 react with the homodinuclear chromium complex [(η5-C5H5)Cr(CO)3]2 with formation of the heterodinuclear derivatives of composition (η5-C5H5)2CrFe(CO)5. (3; single-crystal X-ray structure: d(CrFe) 290.1(1) pm) and (μ-Se2)[(η5-C5H5)2CrFe(CO)4] (4). The latter compound exhibits a diselenido bridge ligand in η1:η2-coordination (single-crystal X-ray structure: d(CrSe) 249.5(2) and 255.5(2) pm, d(FeSe) 238.9(2), d(SeSe) 229.7(1) pm) and can also be obtained by treatment of the chromium complex 3 with elemental selenium.
