The crystal and molecular structure of the neutral adduct of diphenyltriazene (dptH) with rhodium acetate, [Rh2(O2CCH3)4-(dptH)2], was determined. The title compound belongs to the triclinic space group P1 with a = 8.173 (1) ?, b = 8.923 (2) ?, c = 12.191 (1) ?, α = 91.95 (1)°, β = 101.77 (1)°, γ = 101.54 (1)°, V = 850.2 (4) ?3, dcalcd = 1.63 g/m3, Z = 1, and mol wt = 834.46. The structure was refined on 1978 observed reflections to R = 0.077. The structure contains linearly bound diphenyltriazene with Rh-N bond lengths of 2.301 (8) ? and N-N bond lengths of 1.27 (2) and 1.32 (2) ?, with an N-N-N angle of 114 (1)°. The planes of the phenyl rings in one diphenyltriazene ligand are puckered at a dihedral angle of 39.7°. The correlations between the structure and the IR spectra of this complex have been used to assign structures of complexes of rhodium carboxylates with Berenil, a DNA-binding ligand. In this latter case both linear and bridging examples have been identified.
