Abstract
A cadmium compound CdI2(phen)2, (1) (phen = 1,10-phenanthroline), was been synthesized via a hydrothermal reaction and structurally characterized by single-crystal X-ray diffraction. The cadmium ion is coordinated by two terminal iodine ions and four nitrogen atoms from two coordinating phen molecules, constructing a distorted octahedron. Compound 1 features an isolated structure. Photoluminescent study shows that compound 1 exhibits a strong and broad emission in the blue region. Theoretical investigation reveals that the emission can be attributed to ligand to ligand charge transfer.
