Novel complexes between (a) a compound of the formula ##STR1## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are independently H or C.sub.1 -C.sub.3 alkyl; and (b), salts of one of the cations Li, Na, K, Rb, Mg, Ca, Sr, Mn (II), Mn (III), Fe (II), Fe (III), Cu (I), Cu (II), Ag (I), Zn (II), Sn (II), Au (I), Au (II), Hg (I), Hg (II), Ni (I), Ni (II), Co (II), Co (III), hydronium, ammonium alkylammonium and pyridinium; optionally with solvent molecules in the crystal lattice, which complexes are useful as sources of highly pure salts and as soluble sources of certain inorganic reagents, e.g., KMnO.sub.4, NaNO.sub.2, NaSCN, etc., in hydrocarbon systems. For example, a 1:2 complex of sodium chloride and [CH.sub.2 CH.sub.2 O] .sub.4  is formed with 5 molecules of water per sodium cation in the crystal lattice of the complex.
