Abstract

The structure of cis-bis(triphenylphosphine)bis(1,3-diphenyltriazenido)platinum(II) benzene solvate has been determined crystallographically. The square-planar platinum complex is the first definitive example of the monodentate bonding mode for the triazenido ligand. The two crystallographically independent diphenyltriazenido ligands show good agreement in their bond lengths and angles. The average Pt-N distance is 2.089 (6) Å with average N-N lengths of 1.336 (6) Å for the bond adjacent to the Pt and 1.278 (6) Å for the bond away from the metal atom; the N-N-N angle averages 113.9 (5)°. A comparison is made with other reported structures of triazenido complexes. The red-orange crystals of the platinum complex belong to space group P21/n with a = 10.797 (1), b = 23.048 (3), c = 22.034 (3) Å; β = 91.08 (1)°; V = 5482 Å3; Z = 4; pcalcd = 1.44, pobsd = 1.43 g cm-3. The intensity data were collected by counter methods. The structure refined to a conventional R index of 0.045 for the 7923 independent data for which F0 2 > 3σ(F0 2).
