| Abstract: A metal-organic coordination polymer [Cd(ipt)(Medpq)]n(H2ipt=isophthalic acid, Medpq=2-methyldi-pyrido[3,2-f:2′,3′-h]quinoxaline) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, UV-Vis spectrum, TG and single-crystal X-ray diffraction. Title compound crystallizes in the monoclinic system, space group C2/c, with a=2.013 6(4) nm, b=1.608 9(3) nm, c=1.609 3(3) nm, β=125.12(3)°, V=4.302 8(15) nm3, C23H18N4O6Cd, Mr=558.81, Dc=1.725 g·cm-3, Z=8, the final R=0.053 1 and wR=0.140 3. In the crystal structure, the cadmium is six-coordinated with four carboxylate oxygen atoms from three different carboxylate groups, and two nitrogen atoms from Medpq ligand, showing a slightly distorted octahedral geometry. Furthermore, it exhibits a one-dimensional zigzag structure with ipt-Cd-medpq as building units. CCDC: 800998. |
