The crystal structure of dimethyl 4-methoxy-2,3,5,6-tetrachlorophenyl phosphate was determined by X-ray analysis. It crystallized in the space group P2(1)/c (#14) with a = 9.446(2), b = 11.977(2), c = 12.306(2.) Angstrom, beta = 96.55(1)degrees, V = 1383.1(4) Angstrom(3), D-calc = 1,665 5/cm(3), and Z = 4.
