Abstract
A novel ligand N - ethyl - 1,10 - phenanthroline - 2 - methanamine and its Ni(Ⅱ)complex have been synthesized.The crystal structure of the complex has been determined by X - ray diffraction method.The Ni(Ⅱ)is five - coordi - nated by three nitrogen atoms from the ligand and two Cl - anions in a distorted trigonal bipyramidal environment:the N(2),Cl(1)and Cl(2)in equatorial plane;the N(1)and N(3)in axial positions.The UV - spectra and IR - spectra of the ligand and its Ni(Ⅱ)complex were recorded and discussed.The thermodynamic properties of the ligand with various bivalent metals were studied by potentiometric titrations and the order of the stability constants is in a - greement with the Irving - Williams order in coordination chemistry.CCDC:221750.
