| Abstract: | Polynuclear Complexes with Fe? As, Fe? Sb, and Fe? Bi Frameworks The anionic iron clusters Fe3(CO)112? and Fe4(CO)132? were reacted with compounds EX3 and with organic derivatives REX2 and R2EX of the elements arsenic, antimony, and bismuth. Commonly redox and cluster degradation reactions were observed. The new complexes [(CO)4Fe? AsMe2? Fe(CO)4]?, [HFe3(CO)9(mu;3-SbBut)]?, [Fe3(CO)10 (mu;3-Sb)]?, and [Fe3(CO)10(mu;3-Bi)]? were formed and isolated as their PPN salts. The Fe? As? Fe complex was identified by a structure determination, the other complexes were identified by their spectra. |
