Abstract
A new thiocyanato-bridged polymeric cadmium(II) complex with the Schiff base ligand (1-pyridin-2-ylethylidene)pyridin-2-ylmethylamine (L) derived from 2-acetylpyridine and 2-aminomethylpyridine has been prepared and characterized by elemental analyses, IR spectrum, and single crystal X-ray crystallographic determination. The complex crystallizes in the monoclinic space group P21/n with unit cell dimensions a = 8.904(2), b = 12.041(2), c = 15.550(3) A, β = 92.354(2)°, V = 1665.7(5) A3, Z = 4, R1 = 0.0523, and wR2 = 0.1274. The Schiff base ligand coordinates to the Cd atom through the three N atoms. The Cd atom of the complex is heptacoordinated by the Schiff base ligand in a tridentate fashion, one nitrate ligand in a bidentate fashion, and one N and one S atoms from two thiocyanate ligands. The overall coordination is pseudopentagonal bipyramidal geometry. The fluorescence property of the complex was investigated.
