| Abstract: The mononuclear chromium(Ⅲ) complex with 2-hydroxy-1-naphthaldehyde semicarbazone was synthesized and characterized by IR, UV-Vis, fluorescence spectra and single-crystal structure determination. The crystal structure belongs to monoclinic system, space group C2/c with a=3.535 7(8) nm, b=1.608 5(4) nm, c=0.930 52(19) nm, β=98.271(4)°, and Z=8. The crystal structure and spectra data suggest that the ligand of 2-hydro-1-naphthal-dehyde semicarbazone behaves as a tridentate chelating agent, coordinating through phenolic oxygen, nitrogen atom of C=N group and ketonic oxygen. The chromium(Ⅲ) center is a six-coordinated distorted octahedral geometry. CCDC: 647892. |
