Abstract

Sodium salt of N-bromobenzenesulfonamide, C6H5SO2NBrNa 1.5H2O, F.W = 282.07, monoclinic, P21/c, a = 10.499(3) Å, b = 6.750(4) Å, c = 11.802(6) Å, β = 104.08(3)°, V = 1017.4(8) Å3, Z = 4, Dclac = 1.841 gm cm−3, μ = 4.267 cm−1, F 000 = 552, λ(MoKα) = 0.71069 Å, final R1 and ωR2 are 0.116 and 0.279 respectively. The crystal structure shows the dominant motif which can be described as an aquo-bridged sodium dimer (Na-O = 2.4382(2)Å, 2.4392(1)Å). In addition to the bridging of water molecules, the halves of the dimer are held together by a hydrogen bond between a coordinated water molecule and the amido nitrogen. N,N1 -dibromobenzenesulfonamide, C6H5SO2NBr2, F.W = 314.98, monoclinic, P21/c, a = 10.518(5) Å, b = 8.10(1) Å, c = 11.812(6) Å, β = 112.83(4)°, V = 926(1) Å3 Z = 4, D calc = 1.26 gm cm−3, μ = 8.95 cm−1, Fooo = 600, λ(MoKα) = 0.71069 Å, final R and R ω are 0.069 and 0.079 respectively. N,N1 ′-dichlorobenzenesulfonamide, C6H5SO2NCl2, F.W = 226.08, monoclinic, P21 /c, a = 10.42(l)Å, b = 8.098(8)Å, c = 11.697(7)Å, β= 113.03(4)°, V = 908(1) Å3, Z = 4, D calc = 1.65 gm cm−3, μ = 8.94cm−1, F 000 = 456, λ(MoKα) = 0.71069 Å, final R and Rω are 0.04 and 0.044 respectively. N,N1 -dichloro-4-methylbenzenesulfonamide, C7H7SO2NCl2, F.W = 240.10, monoclinic, P21/n, a = 7.179(3) Å, b = 16.217(2) Å, c = 8.692(3) Å, β = 96.69(3)°, V = 1005.1(4) Å3, Z = 4, D calc = 1.598gm cm−3, μ = 8.2cm−1, F 000 = 488, λ(MoKα) = 0.71069Å, final R and R ω, are 0.055 and 0.079 respectively.
