Full title: Stereochemical and electrochemical analyses of the cyclopentadienyl and methylcyclopentadienyl dinitrosyl-capped tricobalt analogues, Co3(η5-C5H5-xMe x)3(μ3-NO)2 (Where x = 0, 1), of the Classical Fischer-Palm Ni3(η5-C5H5) 3(μ3-CO)2. The slow addition of Co(η5-C5H5)(CO)2 to a photolyzed THF solution of the Fe-Fe double-bonded Fe2(η5-C5H5) 2(μ2-NO)2 unexpectedly afforded Co3(η5-C5H5) 3(μ3-NO)2 (1) in 3-5% yield. This 48-electron cluster (previously isolated and spectroscopically characterized) and its methylcyclopentadienyl derivative (2) were found from single-crystal X-ray diffraction analyses to possess analogous Co3(NO)2 cores of D3h-3/m2m geometry (exact for 1 and ideal for 2). Both 1 and 2 were shown from CV measurements to possess similar reversible electron-transfer properties with each neutral parent undergoing a one-electron oxidation to its 47-electron monocation and a one-electron reduction to its 49-electron monoanion.
