Name for analog of salt hydrate with non-water solvents?
The corresponding rule in the Red Book (‘Nomenclature of Inorganic Chemistry – IUPAC recommendations 2005’) reads as follows:


  The names of the individual components of such a generalized addition compound are each constructed by using an appropriate nomenclature system, whether compositional, substitutive or additive. The overall name of the compound is then formed by connecting the names of the components by ‘em’ dashes; the proportions of the components are indicated after the name by a stoichiometric descriptor consisting of arabic numerals separated by a solidus or solidi. The descriptor, in parentheses, is separated from the compound name by a space.
