Topological investigations of the state of a salt in some binary mixtures of non-electrolytes

Abstract

Molar excess volumes have been measured at 308.15 K for pyridine [saturated with anhydrous copper(II) chloride] A (s)–aniline, O-toluidine, formamide or N,N-dimethylformamide (B) mixtures, and these have been rationalized by graph-theoretical arguments to suggest that while copper(II) Chloride(s) in A (s) exists as [graphic omitted], the addition of B to A (s) results in the Formation of molecular entities of the type [graphic omitted]. These conclusions have been supported by molecular weight and infrared spectroscopic studies.
