Abstract

Titanocene bis(acetylide) where the acetylide has ferrocenyl or ruthenocenyl terminal group (C5H4R)(2)Ti{(C=C)(n)-Mc}(2), reacted with 0.5 equivalent amount of AgPF6 giving cationic heptanuclear complexes of the form [(C5H4R)(4)Ti-2{(C=C)(n)-Mc}(4)Ag](PF6) (la: R = SiMe3, n = 1,Me = ferrocenyl, 2a: R = H, n = 2, Me = ferrocenyl, 3a: R = SiMe3, n = 2, Me = ferrocenyl, 4a: R = SiMe3, n = 1, Me = ruthenocenyl) in goodyields. Likewise, complex [(C5H4SiMe3)(4)Ti-2(C=CPh)(4)Ag](PF6) (5a) was isolated. The Ti(IV)-Fe(II)-Ag(I) complex 3a was structurally characterized to confirm the solid-state geometry of the first bis(Ti-tweezers) type chelate complex with silver cation in which the silver was coordinated by four triple bonds of the two titanocene bis(acetylide) moieties. The similar Ti(IV)-Ru(IH)-Ag(I) complex 4a was also characterized by single-crystal X-ray analysis. Complex 3a reacted with 1.5 equivalents (with respect to Ti) of AgPF6 to liberate Fc-(C=C)(4)-Fe (Fc= ferrocenyl) quantitatively. (C) 1998 Elsevier Science S.A. All rights reserved.
