Interfacial Adsorption of Iron(II)–4,7-Diphenyl-1,10-phenanthroline Complex in Ion-Association Extraction Systems

4,7-Diphenyl-2,9-bis­(trichloro­meth­yl)-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) Å, 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).

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

The asymmetric unit of the title compound, C24H16N2·0.5CH3OH, is comprised of two independent bathophenanthroline mol-ecules (systematic name: 4,7-diphenyl-1,10-phenanthroline) and one methanol mol-ecule. The bathophenanthroline mol-ecules 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 rang...

1,2-Diphenyl-1H-imidazo[4,5-f][1,10]phenanthroline

In the title compound, C(25)H(16)N(4), the fused ring system is essentially planar [maximum deviation = 0.1012 (15) Å]. The imidazole ring makes dihedral angles of 77.41 (8) and 56.26 (8)° with the phenyl rings attached to nitro-gen and carbon, respectively. The dihedral angle between the two phenyl rings is 65.50 (8)°. Weak C-H⋯π inter-actions are found in the crystal structure.

(4,7-Diphenyl-1,10-phenanthroline-κ2 N,N′)diiodidomercury(II)

In the mol-ecule of the title compound, [HgI(2)(C(24)H(16)N(2))], the Hg(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from the bidentate 4,7-diphenyl-1,10-phenanthroline and two iodide ligands. There is a π-π contact between the pyridine and phenyl rings [centroid-to-centroid distance = 4.2387 (4) Å].
