Dichlorido(2,9-dimethoxy-1,10-phenanthroline-κ2N,N′)zinc(II)

In the crystal structure of the title compound, [ZnCl2-(C14H12N2O2)], the Zn-II center is four-coordinated by two N atoms from one 2,9-dimethoxy-1,10-phenanthroline ligand and two Cl atoms. The coordination geometry is distorted tetrahedral, as the Zn-N bond distances are shorter than the Zn-Cl distances, and the Cl-Zn-N and Cl-Zn-Cl bond angles are much larger than the N-Zn-N angle. For the ligand, the O and C atoms of the methoxy groups are almost in the plane defined by the phenanthroline ring. The two O atoms deviate from the phenanthroline mean plane by 0.076 (2) and 0.084 (2)angstrom, and the two methyl C atoms deviate from the phenanthroline mean plane by 0.035 (3) and 0.361 (3) angstrom. There are medium pi-pi stacking interactions between two parallel phenanthroline rings with a centroid-centroid distance of 3.7860 (2) angstrom and a dihedral angle between the plane defined by the two parallel phenanthroline rings of 1.13 (5)degrees.
