Summary:The synthsis, crystal structure, thermal analysis and spectroscopic studies of two novel zinc(II) coordination polymers Zn 4 (NA) 4 Dpa 2 ( I ) and Zn(Inic)(Bpdc) 0.5 ( II ) (NA = niacin, Inic = isonictinic acid, Dpa = 2,2′-biphenyldicarboxlate, Bpdc = 4,4′-biphenyldicarboxylate) are presented here. The crystal structure of I is a two-dimensional network whose tetranuclear unit is a slightly distorted square. Two kinds of ligand connect adjacent zinc(II) ions, respectively, in a coordinate direction. The structure of II is a three-dimensional and it consist of corrugated square layers of isonictinic acid-bridged zinc(II) ions which are pillared by 4,4′-biphenyldicarboxylate. The rod-ligands in II appear as useful tools to control the interlayer metal-metal separation. Each zinc(II) ion in I and II is four-coordinated with three oxygen atoms and one nitrogen atom building distorted tetrahedron environments.
