Zinc(II) pyridine-3,4-dicarboxylate polymeric complex with phen, [Zn(PDC)(phen)]n (H2PDC=pyridine-3,4-dicarboxylic acid, phen=1,10-phenthroline) has been synthesized and characterized by means of elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P2(1)/n with a=0.77136 nm, b=1.9757(4) nm, c=1.0680(2) nm, β=95.36(3)°, V=1.6205(6) nm3, Z=4, Dc=1.683 Mg/m3, Mr=410.68, F(000)=832, μ=1.55 mm-1 and R1=0.0608, wR2=0.0967. The X-ray analysis revealed that the central Zn atom is octahedrally coordinated by three O atoms from two PDC ligands, one N atom from another PDC and two N atoms from phen. The resulting ZnN3O3 octahedron is bridged by PDC, forming a 2D layer net structure. In addition, the thermal and luminescent properties of the title compound were also studied.

Key words: coordination polymer, hydrothermal synthesis, crystal structure, luminescent property
