One Cd(II) complex of a new polydentate double Schiff base ligand 1,10-phenanthroline-2,9-dicarboxaldehyde-di-picolinohydrazone (L), [Cd(L)(SCN) 2 ], was synthesized and structurally characterized. This compound belongs to a monoclinic system with space group C2/c. In this monomer, the cadmium metal center is coordinated to four nitrogen atoms and two oxygen atoms from one organic ligand L acting as a hexadentate chelate, and two nitrogen atoms from two distinct SCN − anions, forming an uncommon distorted hexagonal bipyramid coordination geometry. Furthermore, fluorescent and thermal properties of the complex were performed on the powder sample. The complex strongly emits at 467 nm with the excitation of 410 nm and is thermally stable up to 300°C, and thus can be utilized as one potential fluorescent material.
