cis-Bis[1,3-bis(2-fluorophenyl)triazenido-kappa2N1,N3]bis(pyridine-kappaN)cadmium(II).
In the title compound, [Cd(C12H8F2N3)2(C5H5N)2], the Cd atom lies on a crystallographic twofold axis in space group Iba2. The coordination geometry about the Cd(II) ion corresponds to a rhombically distorted octahedron, with two deprotonated 1,3-bis(2-fluorophenyl)triazenide ions, viz. FC6H4NNNC6H4F-, acting as bidentate ligands (four-electron donors). Two neutral pyridine (py) molecules complete the coordination sphere in positions cis with respect to one another. The triazenide ligand is not planar (r.m.s. deviation = 0.204 A), the dihedral angle between the phenyl rings of the terminal 2-fluorophenyl substituents being 24.6 (1) degrees. The triazenide and pyridine Cd-N distances are 2.3757 (18)/2.3800 (19) and 2.3461 (19) A, respectively. Intermolecular C-H.F interactions generate sheets of molecules in the (010) plane.
