A series of L2 = diimine (Bian = bis(3,5-diisopropylphenylimino) acenapthene, But2bpy = 4,4′-di-tert-butyl-2, 2′-bipyridine) supported aqua, hydroxo, oxo, amido, imido, and mixed complexes have been prepared. Deprotonation of [L2Pt(μ-OH)] 22+ with 1,8-bis(dimethylamino)naphthalene, NaH, or KOH yields [(L2Pt)2(μ-OH)(μ-O)]+ as purple (Bian) or red (But2bpy) solids. Excess KOH gives dark blue [(Bian)Pt(μ-O)]2. MeOTf addition to [(But 2bpy)2Pt2(μ-OH)(μ-O)]+ gives [(But2bpy)2Pt2(μ-OH)(μ-OMe)] 2+ while [(Bian)Pt(μ-O)]2 yields [(Bian) 2Pt2(μ-OMe)(μ-O)]+. Treatment of [(Bian)Pt(μ-O)]2 with "(Ph3P)Au+" gives deep purple [(Bian)2Pt2(μ-O)(μ-OAuPPh 3)]+ while (COD)Pt(OTf)2 gives a low yield of [(Bian)Pt3(μ-OH)3(COD)2](OTf)3. Ni(But2bpy)Cl2 and [(Ph3PAu) 3(μ-O)]+ in a 3: 2 ratio yield red [Ni 3(But2bpy)3(μ-O) 2]2+. M(But2bpy)Cl2 (M = Pd, Pt) and [(Ph3PAu)3(μ-O)]+ give [M(But2bpy)(μ-OAuPPh3)]2 2+ and [Pd4(But2bpy) 4(μ-OAuPPh3)]3+. Addition of ArNH 2 to [M(But2bpy)(μ-OH)]2 2+ (M = Pd, Pt) gives [Pt2(But 2bpy)2(μ-NHAr)(μ-OH)]2+ (Ar = Ph, 4-tol, 4-C6H4NO2) and [M(But 2bpy)(μ-NHAr)]22+ (Ar = Ph, tol). Deprotonation of [Pt2(But2bpy) 2(μ-NH-tol)(μ-OH)]2+ with 1,8-bis(dimethylamino) naphthalene or NaH gives [Pt2(But2bpy) 2(μ-NH-tol)(μ-O)]+. Deprotonation of [Pt(Bu t2bpy)(μ-NH-tol)]22+ with KOBut gives deep green [Pt(But2bpy)(μ-N-tol) ]2. The triflate complexes M(But2bpy)(OTf) 2 (M = Pd, Pt) are obtained from M(But2bpy) Cl2 and AgOTf. Treatment of Pt(But2bpy)(OTf) 2 with water gives the aqua complex [Pt(But 2bpy)(H2O)2](OTf)2. This journal is The Royal Society of Chemistry.
