4,7-Diphenyl-1,10-phenanthroline methanol hemisolvate

J. P. Martins, P. Martín-Ramos, A. J. F. N. Sobral and M. Ramos Silva

Abstract: The asymmetric unit of the title compound, C24H16N2·0.5CH3OH, is comprised of two independent bathophenanthroline mol­ecules (systematic name: 4,7-diphenyl-1,10-phenanthroline) and one methanol mol­ecule. The bathophenanthroline mol­ecules are not planar as there is a considerable rotation of all terminal phenyl rings with respect to the central phenanthroline units [dihedral angles in the range 52.21 (12)-62.14 (10)°]. In addition, a non-negligible torsion is apparent in one of the phenanthroline units: the angle between the mean planes of the two pyridine rings is 14.84 (13)°. The methanol solvent mol­ecule is linked to both N atoms of a bathophenanthroline mol­ecule through a bifurcated O-H...(N,N) hydrogen bond.
