Macropolyhedral boron-containing cluster chemistry: Products of the reaction between [{Ru(η6-MeC6H4isoPr)Cl2}2] and syn-[B18H22]. A syn → anti 18-vertex configurational change

Reaction of [{RuCl2(η6-MeC6H4isoPr)}2] with syn-[B18H22] and non-nucleophilic base results in [8-(η6-MeC6H4isoPr)-8-RuB17H21], of 18-vertex anti 10-vertex-nido-10-vertex-nido configuration, as the predominant product. The syn → anti configurational change arises from a trans-cluster pseudo-vertex-substitution of a {BH} vertex by the {Ru2(η6-MeC6H4isoPr)} centre.
