The
anionic 5-acetylimidazol-2-ylidene-4-olate 1–, named as “IMes-acac”, is composed of
fused diaminocarbene and acetylacetonato units in the same IMes-based
imidazolyl ring. The bifunctional compound 1– is shown to act as an effective, ditopic bridging ligand for transition
metal centers. Several new complexes supported by this ligand were
prepared, including the complex [RuCl(p-Cym)(κ2O,O–1·H)](BF4) (2), which can be regarded
as a metallated imidazolium salt, the homobimetallic complex [((COD)Rh)(RhCl(COD))(μ-1κ2O,O:2κ1C–1)] (4), the
heterobimetallic complexes [((p-Cym)ClRu)(RhCl(COD))(μ-1κ2O,O:2κ1C–1)] (3), [((p-Cym)ClRu)(RhCl(CO)2)(μ-1κ2O,O:2κ1C–1)] (5), [((p-Cym)ClRu)(Cu(IPr))(μ-1κ2O,O:2κ1C–1)] (9), the anionic homoleptic Cu(I) complexes
[Cu(κ1C–1)2]K ([10]K) and [Cu(κ1C–1)2](NEt4) ([10](NEt4)), and the heterotrimetallic complex [((p-Cym)RuCl)2(Cu)(μ-1κ2O,O:3κ1C–1)(μ-2κ2O,O:3κ1C–1)](PF6) (11). Preliminary
studies on the possible preparation of supramolecular metallopolymers
and electrochemical studies on the series of complexes are also reported.
