Synthesis, Structural Characterization and Antitumor Activity of a Ca(II)-Schiff Base Complex

A 3D network Ca(Ⅱ) complex has been synthesized in CH3CH2OH solvent,and characterized by elemental analysis,IR spectra,molar conductivity,thermal analysis and X-ray crystal structure determination.The results of crystal structure show that that each Ca(Ⅱ) ion is coordinated with six oxygen atoms from Schiff base ligands(Schiff base derived from 2-carboxybenzaldehyde and diethylenetriamine),forming a distorted octahedral coordination geometry.The compound formed 3D network structure through hydrogen bonds and π-π interaction of benzene rings.The antitumor activity of the Ca(Ⅱ) complex also was investigated.CCDC: 709605.
