phenanthroline%Cu(II) complex%crystal structure%compressed octahedron
The Cu(II) complex with the ligand 2,9-bis(n-2',5'-diazaheptanyl)-1,10-phenan-throline (L) has been synthesized and characterized by single-crystal X-ray diffraction.It crys-tallizes in the monoclinic system,space group P21/n with a = 12.549(4),b = 13.544(4),c = 16.767(5)(A),β = 107.179(5)o,C22H32Cl2N6CuO8,Mr = 642.98,V =2722.5(13)(A)3,Z = 4,Dc = 1.569 g/cm3,μ = 1.056 mm-1,F(000) =1332,the final R = 0.0733 and wR = 0.1581.The X-ray analysis revealed that the Cu(II) ion is coordinated by six nitrogen atoms of the ligand,in which two nitrogen from phenanthroline and another two from the imine groups near phenanthroline are in the equatorial plane while the two from imine groups at the end of both arms in the axial positions.The coordination geometry can be described as a compressed octahedron.
