From the room temperature reaction of (CO)(9)Fe-3(mu(3)-Se)(2) or (CO)(6)Fe-2(mu-Se-2) with diazomethane, four products were isolated; (CO)(3)Fe(mu-CH2)Se}(2) (1), (CO)(6)Fe-2(mu-SeCH3)(2) (2), (CO)(6)Fe-2(mu-SeCH2Se) (3) and (CO)(6)Fe-2(mu-SeCH2CH2Se) (4). All four 77 compounds were characterised by IR, H-1, C-13, and Se-77 NMR spectroscopy. Structures of 1, 3 and 4 were established by single crystal X-ray structure analyses.
