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=1.027 4(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=1.649 g.cm-3,μ(Mo Kα)=1.324 mm-1,F(000)=968,Z=4,the final R=0.038 8 and wR=0.071 7 for 2 697 observed reflections(I>2σ(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.
A metal-organic coordination polymer [Zn (Pht) (Medpq)] n (Pht = phthalic acid, Medpq = 2-methyldipyrido [3,2- f: 2 ’, 3’-h] quinoxaline) 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 = 1.027 4 (4) nm, b = 2.955 7 (11 ) nm, c = 0.685 2 (3) nm, β = 112.941 °, V = 1.9163 (13) nm3, C23H14N4O4Zn, Mr = 475.75, Dc = 1.649 g.cm-3, μ (Mo Kα) = 1.324 mm- 1, F (000) = 968, Z = 4, the final R = 0.038 8 and wR = 0.071 7 for 2 697 observed reflections (I> 2σ (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. Stillrther, it exhibits a one-dimensional structure with Pht-Zn-Medpq as building units. CCDC: 716600.
