A cross-shaped Ag5Ti4 molecule
based on a [Ag(C
N)4]3− core
Abstract
K3[Ag(CN)4] (2) reacts with
{[Ti](C
CR)2}AgOClO3
{R =
SiMe3, 1a; R = Ph, 1b; [Ti] =
(η5-C5H4SiMe3)2
Ti} in a 1∶4 molar ratio to produce the nonametallic
Ag5Ti4 species
[Ag(C
N→Ag{(RC
C)2[Ti]})4
](ClO4) (R = SiMe3, 3a; R = Ph, 3b) in which
four heterobimetallic titanium(IV)–silver(I)
tweezer units, [{[Ti](C
CR)2}Ag]+,
are bridged by a [Ag(C
N)4]3− core; the
reaction chemistry of 3 is reported.
