Isomeric clusters [Ru 4(µ 4-PPh)(µ 4-C 4H 3N)(CO) 11] containing diagonal C,C and parallel C,N bonded pyrrolyne ligands
Abstract
The three isomeric tertiary phosphines, diphenyl- n-pyrrolylphosphine ( n = 1, 2 or 3) lead to two isomeric tetranuclear clusters [Ru 4(µ 4-PPh)(µ 4-C 4H 3N)(CO) 11] which contain the diagonal C,C bonded and parallel C,N bonded pyrrolyne ligands.
