Although the N-p-methoxyphenyl-substituted 1,2,4-diselenazolidine C reacted with Fe3(CO)12 to give the expected butterfly [2Fe2Se] complex [(μ-SeCH2)2NC6H4OMe-p]Fe2(CO)6 (5) and further reaction of 5 with PPh3 afforded its PPh3-substituted derivative [(μ-SeCH2)2NC6H4OMe-p]Fe2(CO)5(PPh3) (6), the N-arylmethyl-substituted
