Aj. Arce et al., ISOMERIC CLUSTERS [RU-4(MU(4)-PPH)(MU(4)-C4H3N)(CO)(11)] CONTAINING DIAGONAL C,C AND PARALLEL C,N BONDED PYRROLYNE LIGANDS, Chemical communications, (2), 1998, pp. 233-234
The three isomeric tertiary phosphines, diphenyl-n-pyrrolyl-phosphine(
n = 1, 2 or 3) lead to two isomeric tetranuclear clusters [Ru-4(mu(4)-
PPh)(mu(4)-C4H3N)(CO)(11)] which contain the diagonal C,C bonded and p
arallel C,N bonded pyrrolyne ligands.
