A metal-organic Complex [Cu_2(ipt)(Medpq)_2]_n (ipt=isophthalic 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 single-crystal X-ray diffraction. Title compound crystallizes in the monoclinic system, space group C2/c, with a=2.389 2(6) nm, 6=0.709 60(18) nm, c=1.922 2(5) nm, β=108.655(3), V =3.087 8(14) nm~3, C_(38)H_(24)Cu_2 N_8O_4, M_r=783.73, D_c=1.686 g·cm~(-3), Z=4, the final R=0.0554 and wR=0.1285. In the crystal structure, the copper atom is three-coordinated with one carboxylate oxygen atom from carboxylate groups and two nitrogen atoms from Medpq ligand, showing a slightly distorted triangle geometry. Furthermore, it exhibits a zero-dimensional structure with ipt-Cu- medpq as building units.
