title: Crystal structure of poly[bis-(μ2-5-hydroxy-nicotinato-κ(2) N:O (3))zinc].
abstract: The title coordination polymer, [Zn(C6H4NO3)2] n , was prepared under hydro-thermal conditions by the reaction of zinc nitrate with 5-hy-droxy-nicotinic acid in the presence of malonic acid. In the structure, the Zn(II) ion is coordinated by two carboxyl-ate O atoms and two pyridine N atoms of four 5-hy-droxy-nicotinate ligands in a distorted tetra-hedral coordin-ation environment. The μ2-bridging mode of each anion leads to the formation of a three-dimensional framework structure. Inter-molecular hydrogen bonds between the hy-droxy groups of one anion and the non-coordinating carboxyl-ate O atoms of neighbouring anions consolidate the crystal packing.
