Abstract
Five novel coordination polymers containing N-[(3-carboxyphenyl)-sulfonyl]glycine (H3L), namely [Co3L2(μ2-bipy)2(H2O)6]n·2nCH3OH·8nH2O (1), [Mn(HL)(μ2-bipy)(H2O)2]n·nH2O (2), [Mn(HL)(μ2-bipy)(H2O)]n·3nH2O (3), [Mn(HL)(bipy)(μ2-bipy)0.5(H2O)]n·4nH2O (4), [Ca(H2O)4Cu2(μ2-bipy)2L2]n·4nH2O (5) (bipy = 4,4′-bipyridine), were prepared under control by tuning the reaction conditions such as pH value, reaction temperature, and starting materials. X-ray structural analyses of 1–5 reveal their structural diversity ranging from one-dimensional (1D) (1), two-dimensional (2D) (2), and noninterpenetrating 3-D porous coordination polymers (3, 4) to a 2-fold 3D interpenetrating network (5). Compound 1 presents a 1D chain structure with alternating [CoL(H2O)]22− binuclear and [Co(4,4′-bipy)2(H2O)4]2+ mononuclear units along the a-axis. Polymer 2, which was formed at a comparatively lower temperature, has a 2D structure extended by a HL2− ligand and a monopillar of bipy. A higher temperature was used in the preparation of ...
