Abstract

The structure of hydrido(dinitrogen)bis[phenyl(di-tert-butyl)phosphine]rhodium(I), RhH(N₂)[P(C₆H₅)(C₄H₉)₂]₂, has been determined crystallographically. The complex possesses a typical four-coordinate planar geometry about Rh with a slight bending of the phosphine groups toward the hydrido ligand (P-Rh-P = 168.12 (3)°). A linear H-Rh-N-N arrangement is required by the crystallographically imposed twofold axis. The compound crystallizes in space group C_2h⁶-C2/c of the monoclinic system with four formula units in a cell of dimensions a = 22.187 (2) Å, b = 8.340 (1) Å, c = 15.979 (2) Å, and β = 93.108 (6)°. Important distances are Rh-P = 2.297 (1) Å, Rh-H = 1.66 (5) Å, Rh-N = 1.970 (4) Å, and N-N = 1.074 (7) Å. The structural data were refined by full-matrix least-squares methods to a conventional R index of 0.034 based on those 2760 reflections having F₀² > 3σ(F₀²).
