A mono-complex has been synthesized by the reaction of 2,6-dicarboxamido-(2-pyridyl)-pyridine(H2pdcap) and CuCl2.X-ray diffraction technique reveals that the central Cu(II) ion lies in a distorted trigonal bipyramid geometry.The crystal is assigned to triclinic with space group Pī.The cell parameters are:a=0.8614(17);b=1.0621(2);c=1.0647(2);α=76.65(3)°;β=82.46(3)°;γ=82.58(3)°.The powder SHG effect of the title complex is 1.3 times than that of carbamide.
