The clusters Fe4(CO)11(PR)2 (1) are reduced by PhLi to produce radical anions which react with Et3OBF4 to give neutral radical clusters [Fe4(CO)10(PR)2(mu-COEt)]. (2) in which a CO group of the starting compounds is alkylated to yield a mu-2-COEt ligand. Structure analysis of 2a (R = (t)Bu) demonstrates that the framework geometry of 2 is almost identical to the one observed for 1: the additional electron present in 2 as compared to 1 occupies an essentially non bonding cluster orbital.

(2) in which a CO group of the starting compounds is alkylated to yield a mu-2-COEt ligand. Structure analysis of 2a (R = (t)Bu) demonstrates that the framework geometry of 2 is almost identical to the one observed for 1: the additional electron present in 2 as compared to 1 occupies an essentially non bonding cluster orbital. The results are further substantiated by electrochemical investigations and EPR spectroscopy. » weiterlesen» einklappen
