The crystal and molecular structures of 1-(N-dichlorophosphoryl-N-cyclohexyl) amino-1-dichlorophosphinyl-chloromethane have been determined by X-ray diffraction. The crystal (C7H12Cl5NO2P2) is of orthorhombic, space group Pbca with a = 11.104(7), b = 11.290(6), c = 24.403(14) A, V = 3059(3) A3, Mr = 381.37, Z = 8, Dc = 1.656 g/cm3, μ = 1.146 mm-1, F(000) = 1536, the final R = 0.0391 and Rw = 0.0778 for 2657 observed reflections with I > 2σ(I). The crystallographic results of the title compound show that the N atom is not a conventionally sp3 hybridized tetrahedron but an sp2 hybridized triangular planar nitrogen.
