4,7-Diphenyl-2,9-bis-(trichloro-meth-yl)-1,10-phenanthroline.

In the title compound, C(26)H(14)Cl(6)N(2), the phenanthroline ring system is essentially planar, with an r.m.s. deviation of 0.048†(6)†à , and makes dihedral angles of 64.8†(14) and 66.6†(6)° with the two terminal phenyl rings. One of the trichloro-methyl groups is disordered over two positions, with occupancies of 0.42†(2) and 0.58†(2).
