Abstract

The title compound [Pt(P(C2H5)3)2(H2NNHC6H4F)Cl][BF4] is part of a system proposed as a model, for the reduction of dinitrogen to ammonia. The structure of the complex has been determined at room temperature from three-dimensional X-ray data collected by counter methods. The structure has been refined by full-matrix least-squares techniques to a final R index (on F) of 0.045 based on 3015 reflections above background. The material crystallizes in the orthorhombic space group D2h 16-Pnma with four molecules in a cell of dimensions a = 16.062 (7), b = 13.625 (6), and c = 12.085 (5) Å. The ions have crystallographically imposed mirror symmetry and the platinum atom has square-planar coordination with Pt-P = 2.328 (2) Å, Pt-Cl = 2.303 (2) Å, and Pt-N(1) = 2.081 (7) Å. The hydrazine ligand, including the phenyl group, lies in a plane approximately perpendicular to the coordination plane. The N(1)-N(2) bond is 1.436 (11) Å and the Pt-N(1)-N(2) angle is 113.2 (5)°. There is an extensive hydrogen-bonding system connecting the anions and cations. The structure of this reduced species is compared with structures of other complexes in the same model system.
