A sterically hindered carboxylate ligand is used to synthesize the first transition metal complex containing both bis-mu-oxo and bis-mu-carboxylato groups, [Mn2(mu-O)2(mu-ArtolCO2)2(bpy)2]+. However, methyl substitution on the chelating bipyridine ligand results in the formation of a strikingly different and novel hexanuclear species, [Mn6(mu-O)4(mu3-O)4(mu-ArtolCO2)2(dmb)6]4+. Steric interactions between the bridging carboxylates and chelating pyridine-based ligands determine the nuclearity of the complexes formed.
一种空间位阻羧酸盐配体用于合成首个同时含有双-μ-氧和双-μ-羧基的过渡金属配合物[Mn2(μ-O)2(μ-阿托酸根)2(bpy)2]+。然而，螯合联吡啶配体上的甲基取代导致形成了一种截然不同的新型六核物种[Mn6(μ-O)4(μ3-O)4(μ-阿托酸根)2(dmb)6]4+。桥连羧酸盐与螯合吡啶基配体之间的空间相互作用决定了所形成配合物的核数。
