The crystal structure of the complex of 2-mercuri-4-methylphenol and 2-nitroso-4-methylphenol obtained in the modified Millon reaction was determined using three-dimensional X-ray diffraction data. The complex crystallizes in triclinic system, space group <I>P</I>\bar1, with a unit cell of dimensions <I>a</I>=10.26 Å, <I>b</I>=22.71 Å, <I>c</I>=5.61 Å, α=97.2°, β=93.1°, γ=91.1°, containing four complex molecules. Each of the two crystallographycally independent complex molecules both having essentially the same structure, forms a dimer with its nearest neighbor related by a center of symmetry through a pair of hydrogen bonds. The mercury atoms adopt a planar four-fold coordination with nitrogen, carbon and two oxygen atoms.
