In the solid-state structure of the title compound, C(4)H(12)N(+).C(14)H(10)Cl(2)NO(2)(-).H(2)O, the asymmetric unit contains one cation, one anion and a water molecule. A complex network of hydrogen bonds is present. A comparison is made with the structure of the anhydrous salt.

Excess molar enthalpies, densities and excess molar volumes for binary mixtures containing dimethyl carbonate or diethyl carbonate + 2,2,4-trimethylpentane at 288.15, 298.15, and 313.5 K, and at atmospheric pressure. Application of an extended cell model

Abstract Excess molar enthalpies, H E m , densities, ϱ, and excess molar volumes, V E m , of dimethyl carbonate or diethyl carbonate + 2,2,4-trimethylpentane have been determined at 288.15, 298.15 and 313.15 K and at atmospheric pressure, using an LKB flow microcalorimeter and an Anton Paar digital density meter. For all mixtures, the H E m and V E m values are positive and increase slowly as the temperature is increased. The experimental values have been correlated by the Redlich-Kister equation and the adjustable parameters have been evaluated by least-squares analysis. The results are discussed qualitatively in terms of molecular interactions and have been interpreted by an extended cell model.
