The synthesis, chemical characterisation and single crystal X-ray structural study of the bis-toluene hexaruthenium carbidocarbonyl cluster [Ru6C(CO)(1)1(eta(6)-C(6)H(5)Me)(mu(3)-eta(2):eta(2):eta(2)-C(6)H(5)Me)] is reported. A variable temperature H-1 n.m.r. study reveals that in solution the complex exists in two isomeric forms, one of them, that observed in the solid state and the solid state and the other the trans-[Ru6C(CO)(1)1(eta(6)-C(6)H(5)Me)(2)] isomer. Interchange of the toluene ligand between the mu(3)-eta(2):eta(2):eta(2) and eta(6) co-ordination mode if confirmed by deuterum labelling experiments involving C6D5CD3.

Abstract
The synthesis, chemical characterisation and single crystal X-ray structural study of the bis-toluene hexaruthenium carbidocarbonyl cluster [Ru6C(CO)(1)1(eta(6)-C(6)H(5)Me)(mu(3)-eta(2):eta(2):eta(2)-C(6)H(5)Me)] is reported. A variable temperature H-1 n.m.r. study reveals that in solution the complex exists in two isomeric forms, one of them, that observed in the solid state and the solid state and the other the trans-[Ru6C(CO)(1)1(eta(6)-C(6)H(5)Me)(2)] isomer. Interchange of the toluene ligand between the mu(3)-eta(2):eta(2):eta(2) and eta(6) co-ordination mode if confirmed by deuterum labelling experiments involving C6D5CD3.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
