A metal-organic coordination polymer[Zn(Pht)(Medpq)]n(Pht=phthalic acid,Medpq=2-methyldipyrido [3,2-f:2',3'-h]quinoxaline)(1)has been hydrothermally synthesized and structurally characterized by elemental analysis,IR spectrum,TG and X-ray single-crystal structure analysis.Title complex crystallizes in the monoclinic system,space group Cc,with a=1.0274(4)nm,b=2.955 7(11)nm,c=0.685 2(3)nm,β=112.941°,V=1.916 3(13)nm3,C23H14N4O4Zn,Mr=475.75,Dc=1.649g·cm3,μ(Mo Kα)=1.324mm-1,F(000)=968,Z=4,the final R=0.0388 and wR=0.071 7 for 2 697 observed reflections(I＞2δ(I)).In the crystal structure,the Zinc atom is six-coordinated with four carboxylate oxygen atoms from two different carboxylate groups and two nitrogen atoms from Medpq ligand, showing a slightly distorted octahedral geometry.Furthermore,it exhibits a one-dimensional structure with Pht-Zn-Medpq as building units.CCDC:716600.
