Construction of Co(II), Cu(II), and Zn(II) coordination compounds driven by a pyridine-dicarboxylic acid: Hydrothermal assembly, structural and topological versatility, and catalytic properties
A derivative of pyridine-dicarboxylic acid, 5-(3-carboxyphenyl)picolinic acid (H2cpic), was used as a versatile building block to synthesize a series of five novel coordination compounds under hydrothermal conditions and formulated as {[Cu2(μ-cpic)2(phen)]·H2O}n (1), [Co(μ-cpic)(phen)(H2O)]n (2), [Cu2(μ-cpic)2(2,2′-bipy)(H2O)2]·2H2O (3), {[Cu3(μ-cpic)3(μ-4,4′-bipy)1.5(H2O)3]·2H2O}n (4), and {[Zn2(μ-cpic)2(μ-dpe)0.5(H2O)3]·H2O}n (5). The auxiliary ligands used in the synthesis were 1,10-phenanthroline (phen), 2,2′-bipyridine (2,2′-bipy), 4,4′-bipyridine (4,4′-bipy), and 1,2-di(4-pyridyl)ethylene (dpe). The structures of the compounds 1–5 vary significantly, ranging from a 0D tetramer (3) to 1D metal–organic chains (1, 2, 4, and 5). Furthermore, these compounds were evaluated as heterogeneous catalysts for the Henry reaction, achieving high product yields under optimized conditions. We further investigated various reaction parameters, and substrate scope, and assessed the feasibility of catalyst recycling. This thorough investigation highlights the versatility of H2cpic as a dicarboxylate building block in the formation of functional coordination polymers.
期刊介绍：
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
