Abstract

The reaction of the dinuclear complex Co2(bpy)2(OOCBut)4 with the tetranuclear complex Ni4(μ3-OH)2(OOCBut)6(EtOH)6 afforded the trinuclear heterometallic complex M3(bpy)2(μ3-OH)(μ-OOCBut)4(OOCBut) (6) (M = Ni, Co; Ni : Co = 1.2 : 1) in which two metal atoms are in an octahedral environment and one metal atom is in a tetrahedral environment. The reaction of 2,2"-bipyridine with Co4(μ3-OH)2(OOCBut)6(HOEt)6 (reagent ratio was 2 : 1) or the reaction of bpy with Co8(μ4-O)2(μ n -OOCBut)12 (reagent ratio was 4 : 1) produced a homometallic analog of 6, viz., the trinuclear cluster Co3(bpy)2(μ3-OH)(μ-OOCBut)4(OOCBut) (8). The reaction of 1,10-phenanthroline (phen) with the [Co(OH) n (OOCBut)2–n ] x polymer gave the analogous trinuclear cluster (phen)2Co3(μ3-OH)(μ2-OOCBut)4(η1-OOCBut). Compounds 6 and 8 exhibit antiferromagnetic spin-spin exchange interactions.
