Abstract

Reaction of [(η3-C4H7)2Rh(CH3CN)2]PF63-C4H7 = β-methallyl) with [n-Bu4N](VO3) gives a new η3-allyl cluster [n-Bu4N]2[{(η3-C4H7)2Rh}2 (V4O12)] (I) which is readily converted into a diene cluster, [n-Bu4N]2 [{(η4-C8H14)Rh}2(V4O12)] (II) (C8H14=2,5-dimethyl-1,5-hexadiene) by reacting with CO or P(OEt)3;I andII have been characterized crystallographically.

    There is another example of the η3-allylmetallic oxide cluster [(SiW11O39Sn)2Pd(η3-C3H5)]11− which has not been structurally characterized and it is suggested that the Pd(η3-C3H5) moiety might be bound to the oxide anion through the Sn atom: W.

    Two conformational isomers of the V4O4 ring have been reported so far. One of them has a bent structure, the boat-boat type (BB), which exists in [n-Bu4N]3[HV4O12]: J. Fuchs, S. Mahjour, and J. Pickardt (1976).Angew. Chem. Int. Ed. Engl. 15, 374. The other has a more planar configuration, the twisted chair type (TC), in [{(η4-C8H12)Ir}n(V4O12)](4−n)− (n=1 and 2) [4].Google Scholar
