Monomeric bis(η2-alkyne) complexes of (η1-mesityl)copper(I) and (η1-mesityl)silver(I) obtained from a bis(alkynyl)titanocene; X-ray structure of [(η5-C5H4SiMe3)2Ti(C
CSiMe3)2]Cu(η1-Mes)(Mes = C6H2Me3-2,4,6)
Abstract
Polynuclear mesitylcopper and mesitylsilver react with [(η5-C5H4SiMes3)2Ti(CCSiMe3)2]1 to afford the monomeric complexes [1·Cu(η1-Mes)]2, and [1·Ag(η1-Mes)]3, in which both alkyne moieties of the 3-titanopenta-1,4-diyne unit are η2-coordinated to a MesCu(Ag) unit.
