POLYSULFONYL AMINES .46. MOLECULAR ADDUCT S 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/petrol eum ether, the following crystalline addition compounds were obtained: (X-C6H4SO2)2NH . OS(CH3)2, where X = H, 4-CH3, 4-Cl, 4-Br, 4-1, 4-NO2 Or 3-NO,; [(4-F-C6H4SO2)2NH]2 . OS(CH)3)2 (8); (4-1-C6H4SO2)2NH . OP( C6H5)3. A (2/1) complex of (4-F-C6H4SO2)2NH with OP(CH5)3 could not be isolated. The solid-state structure of the (2/1) compound 8 is compar ed with the known structure of the (1/1) complex (CH3SO2)2NH - OS(CH3) 2. The crystallographic data for 8 at -95-degrees-C are: monoclinic, s pace group C2/c, a = 2369.9(13), b = 1006.8(4), c = 2 772.6(13) pm, be ta = 11 0.71(4)-degrees, U = 6.187 nM3, Z = 8. Two N-H ... 0 hydrogen bonds with N ... 0 275 and 280 pm connect the disulfonylamine molecule s with the dimethyl sulfoxide molecule. The 0 atom of the latter has a trigonal-planar environment consisting of the S atom and the two hydr ogen bond H atoms.
