Strike while the iron is hot! Reaction of [Fe(cot)(CO)3] (COT=cyclooctatetraene) with K4Ge9 yielded [K(2,2,2-crypt)]3[Ge8Fe(CO)3] (see scheme; 2,2,2-crypt=4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane). In addition, a reduction product of the [Fe(cot)(CO)3] precursor was also isolated, [K(2,2,2-crypt)][Fe(η3-C8H8)(CO)3]. All species were characterized by EPR and IR spectroscopy and ES-MS spectrometry when possible.
