摘要:

Sodium salt ofN-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,F000= 552, λ(MoKα) = 0.71069 Å, finalR1and ωR2are 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.

摘要:

Equilibrium phase diagrams of the toluene-hexafluorobenzene and thep-xylene-hexafluorobenzene binary systems are experimentally determined by differential scanning calorimetry and X-ray diffraction analyses. Both diagrams present a complex 1:1 with a rich polymorphism. The optimization of these systems shows the existence of high associated degree in the liquid phase. The comparison of these two systems with the benzene-hexafluorobenzene binary shows that the complex stability increases with number of H-atoms substituted by CH3-methyl groups in the benzenic ring.
