One phosphorus heterocycle compound 1, C13H13N2OPS, was synthesized by the reaction of Lawesson’s reagent (LR) with o-phenylene diamine. The crystal belongs to the orthor- hombic system, space group P212121 with a = 5.5274(11), b = 8.1603(16), c = 28.830(6) ?, V = 1300.4(4) ?3, Z = 4, Mr = 276.28, Dc = 1.411 g/cm3, F(000) = 576, μ = 0.360 mm-1, R = 0.0259 and wR = 0.0652 for 1414 observed reflections with I > 2σ(I). While compound 2, C14H17N2O2PS, was obtained as a ring-cleavage product of compound 1. This crystal is of monoclinic system, space group P21/c with a = 9.5619(19), b = 21.879(4), c = 7.3618(15) ?, β = 103.03(3)°, V =1500.4(5) ?3, Z = 4, Mr = 308.33, Dc = 1.365 g/cm3, F(000) = 648, μ = 0.325 mm-1, R = 0.0383 and wR =0.0742 for 2283 observed reflections with I > 2σ(I). Phosphorus atom in each compound bonds with sulfur and carbon atoms using sp3 hybrid orbitals, and crystals of these two compounds are formed and sta- bilized by intermolecular hydrogen bonds and Van der Waals’ forces. The special structure of com- pound 1 leads to its good antimicrobial activity against staphylococcus aureus.
