中文摘要	reactions of zn(bf4)(2) and pyridine-2,4-dicarboxylic acid (2,4-pydch(2)) in the presence of 1,2-bis( 4-pyridyl) ethylene or 1,3-bis(4-pyridyl) propane under hydro(solvo) thermal conditions yielded two polymorphic metal-organic coordination polymers formulated as zn-2(oh)(2)(2,4-pydc) (1 and 2). polymorph 1 features a two-dimensional (2-d) layer-like structure that is constructed by 2,4-pydc ligands bridging between the zn-oh-zn double-chain units. each single zn-oh-zn chain is composed of mu(2)-oh groups connecting trigonal bipyramidal and tetrahedral zn centers. polymorph 2 is a 3-d coordination polymer containing 2-d zn-oh-zn sheets that consist of mu(2)- and mu(3)-oh groups and trigonal bipyramidal zn centers. the sheets are pillared by 2,4-pydc ligands to form an acentric structural architecture. 1 and 2 are rare examples that the two polymorphs exhibit a centrosymmetric 2-d coordination network and an acentric 3-d coordination network, respectively. the different structures lead to differences in photoluminescent properties and thermal stabilities for 1 and 2.
