Abstract

The reaction of the dinuclear complex Co2(μ-OOCCMe3)2(η2-OOCCMe3)2bpy2 (1) with the polymer [Co(OH) n (OOCCMe3)2–n ] x afforded the unsymmetrical dinuclear complex bpyCo2(μ2-O,η2-OOCCMe3)(μ2-O,O"-OOCCMe3)2(η2-OOCCMe3) (2). The reaction of 2,2"-dipyridylamine with [Co(OH) n (OOCCMe3)2–n ] x gave rise to the analogous complex [(C5H4N)2NH]Co2(μ2-O,η2-OOCCMe3)(μ-OOCCMe3)2(η2-OOCCMe3) (3). The reaction of complex 1 with Ni4(μ3-OH)2(μ-OOCCMe3)4(OOCCMe3)2(MeCN)2[η2-o-C6H4(NH2)(NHPh)]2 (4) produced an isostructural heterometallic analog of complex 2 with composition bpyM2(μ2-O,η2-OOCCMe3)(μ2-O,O"-OOCCMe3)2(η2-OOCCMe3) (5) (M = Co, Ni; Co : Ni = 1 : 1) and the dinuclear heterometallic complex bpy(HOOCCMe3)M(μ-OH2)(μ-OOCCMe3)2M(OOCCMe3)2[o-C6H4(NH2)(NHPh)] (6) (M = Co, Ni; Co : Ni = 0.15 : 1.85). Compounds 2 and 5 exhibit ferromagnetic spin-spin exchange interactions.
