Abstract

Reactions of two equivalents of the lithium amidinate salts Li[tBuC(NR)(2)] (R = iPr, cyclohexyl) with FeCl2 have been found to yield paramagnetic bis(amidinate) iron(II) compounds of the type [tBuC(NR)(2)](2)Fe. In the caseof R = cyclohexyl, the product has been characterized by single-crystal X-ray diffraction analysis as having a distorted tetrahedral geometry. The derivative with R = iPr is an oil, but its H-1 and C-13 NMR spectra indicate a similar monomeric structure. Both species have been found to react readily with CO to give the new diamagnetic Fe-II dicarbonyls [tBuC(NR)(2)](2)Fe(CO)(2). The compound with R = iPr has been structurally characterized, which showed it to have a strongly distorted octahedral structure with the carbonyls in a cis arrangement.
