| Abstract: | Polysulfonyl Amines. XLVI. Molecular Adducts of Di(organosulfonyl)amines with Dimethyl Sulfoxide and Triphenylphosphine Oxide. X-Ray Structure Determination of Di(4-fluorobenzenesulfonyl)amine-Dimethyl Sulfoxide(2/1) From equimolar solutions of the respective components in CH2Cl2/petroleum ether, the following crystalline addition compounds were obtained: (X? C6H4SO2)2NH …? OS(CH3)2, where X = H, 4? CH3, 4? Cl, 4? Br, 4? I, 4? NO2 or 3? NO2; (4? F? C6H4SO2)2NH]2 · (OS(CH)3)2 ( 8 ); (4? I? C6H4SO2)2NH · OP(C6H5)3. A (2/1) complex of (4? F? C6H4SO2)2NH with OP(C6H5)3 could not be isolated. The solid-state structure of the (2/1) compound 8 is compared with the known structure of the (1/1) complex (CH3SO2)2NH · OS(CH3)2. The crystallographic data for 8 at ?95°C are: monoclinic, space group C2/c, a = 2 369.9(13), b = 1 006.8(4), c = 2 772.6(13) pm, β = 110.71(4)°, U = 6.187 nm3, Z = 8. Two N? H …? O hydrogen bonds with N …? O 275 and 280 pm connect the disulfonylamine molecules with the dimethyl sulfoxide molecule. The O atom of the latter has a trigonal-planar environment consisting of the S atom and the two hydrogen bond H atoms. |
