New molecular architectures containing low-valent cluster centres with di- and trimetalated 2-vinylpyrazine ligands: synthesis and molecular structures of Ru(5)(CO)(15)(μ(5)-C(4)H(2)N(2)CH[double bond, length as m-dash]CH)(μ-H)(2) and Ru(8)(CO)(24)(μ(7)-C(4)H(2)N(2)CH[double bond, length as m-dash]C)(μ-H)(3)

Reaction of 2-vinylpyrazine with Ru(3)(CO)(12) results in multiple C–H bond activations to afford penta- and octa-ruthenium clusters, Ru(5)(CO)(15)(μ(5)-C(4)H(2)N(2)CH[double bond, length as m-dash]CH)(μ-H)(2) (2) and Ru(8)(CO)(24)(μ(7)-C(4)H(2)N(2)CH[double bond, length as m-dash]C)(μ-H)(3) (3), in...

description Reaction of 2-vinylpyrazine with Ru(3)(CO)(12) results in multiple C–H bond activations to afford penta- and octa-ruthenium clusters, Ru(5)(CO)(15)(μ(5)-C(4)H(2)N(2)CH[double bond, length as m-dash]CH)(μ-H)(2) (2) and Ru(8)(CO)(24)(μ(7)-C(4)H(2)N(2)CH[double bond, length as m-dash]C)(μ-H)(3) (3), in which a Ru(3) sub-unit is linked to Ru(2) and Ru(5) centres via di- and tri-metalated 2-vinylpyrazine ligands, exhibiting novel coordination modes including the loss of ring aromaticity in 2. The bonding of 2 and the mechanism for the fluxional behaviour of the hydrides have been examined by electronic structure calculations.
