Structural transformation mediated by o-, m-, and p-phthalates from two to three dimensions for manganese/phthalate/4,4'-bpy complexes (4,4'-bpy = 4,4'-bipyridine)

摘要

Three isomers of o-, m-, and p-phthalate are used to link together Mn centres, resulting in [Mn(phth)(H_2O)_x]_n moieties (phth = phthalate dianion) with single-chain, double-chain and sheet structures, respectively, which predetermine the extended structures derived from the crosslinkage of 4,4'-bipyridine, and show the influence of isomerism of the phthalate on topological changes of the final polymers from two dimensional (2D) single-layer, double-layer to 3D network architectures. These structural changes in topology are correlated with the differences in the magnetic and optical properties of the polymers.
