title: trans-Bis[3-(2-fluorophenyl)-1-(4-nitrophenyl)triazenido-kappaN3]bis(pyridine-kappaN)palladium(II).
abstract: In the title complex, [Pd(C(12)H(8)FN(4)O(2))(2)(C(5)H(5)N)(2)] or trans-[Pd(FC(6)H(4)N=N-NC(6)H(4)NO(2))(C(5)H(5)N)(2)], the Pd atom lies on a centre of inversion in space group P-1. The coordination geometry about the Pd(2+) ion is square planar, with two deprotonated 3-(2-fluorophenyl)-1-(4-nitrophenyl)triazenide ions, FC(6)H(4)N=N-NC(6)H(4)NO(2)(-), acting as monodentate ligands (two-electron donors), while two neutral pyridine molecules complete the metal coordination sphere. The whole triazenide ligand is not planar, with the largest interplanar angle being 16.8 (5) degrees between the phenyl ring of the 2-fluorophenyl group and the plane defined by the N=N-N moiety. The Pd-N(triazenide) and Pd-N(pyridine) distances are 2.021 (3) and 2.039 (3) A, respectively.
