An unusual three-center N-H?Cl2Au hydrogen bond is present in the solid state in the title complex, which was characterized by elemental analysis and IR and 1H NMR spectroscopy. The crystal and molecular structure has been determined by a single-crystal X-ray analysis. The compound crystallizes in the space group P1 with a = 9.380(2) ?, b = 10.219(3) ?, c = 11.678(4) ?, α = 89.33(2)°, β = 68.85(2)°, and γ = 64.67(2)°. Mo Kα radiation was used. The data suggest that M-Cl?H angles of ca. 90° are favorable for H-bonding, which is ascribed to the greater basicity of p-type lone pairs versus sp-type. The possibility of synthesizing hydrogen halide complexes is discussed.
