Abstract
The reaction between Na[HFe(CO) 4 ] and (PhSe) 2 Yielded Na[Fe(CO) 3 (SePh) 3 ] which crystallized as [Na·3thf][Fe(CO) 3 (SePh) 3 ] in which three tetrahydrofuran (thf) molecules and the [Fe(CO) 3 (SePh) 3 ] - anion surround the sodium cation; in the corresponding crystal structure of [N(PPh 3 ) 2 ][Fe(CO) 3 -(SePh) 3 ]·0.5thf the cations and anions are discrete entities.
