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)(H2O)x]n moieties (phthâ=âphthalate dianion) with single-chain, double-chain and sheet structures, respectively, which predetermine the extended structures derived from the crosslinkage of 4,4â²-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.
