<SUP>17</SUP>O NMR spectra have been measured for series of cobalt carbonyl cluster derivatives, RCCo<SUB>3</SUB>(CO)<SUB>9−<I>x</I></SUB>(PPh<SUB>3</SUB>)<I><SUB>x</SUB></I>, (RC<SUB>2</SUB>R′)Co<SUB>3−<I>x</I>−<I>y</I></SUB>Fe<I><SUB>x</SUB></I>Mo<I><SUB>y</SUB></I>(CO)<SUB>9−<I>y</I></SUB>Cp<I><SUB>y</SUB></I>, and R<SUB>3−<I>x</I></SUB>Sn[Co(CO)<SUB>4</SUB>]<SUB><I>x</I>+1</SUB>. The small <SUP>17</SUP>O-chemical shift differences due to the change of R and/or introduction of PPh<SUB>3</SUB> have been interpreted in terms of the electron buffer action of the Co<SUB>3</SUB> core for RCCo<SUB>3</SUB>(CO)<SUB>9−<I>x</I></SUB>(PPh<SUB>3</SUB>)<I><SUB>x</SUB></I>. Good linear correlations between <SUP>17</SUP>O-chemical shifts and CO stretching frequencies have been observed for these derivatives. Some effect of the magnetic anisotropy resulted from the ring current along the metal-triangle on <SUP>17</SUP>O-chemical shifts has been suggested for metal-triangle clusters.
