Claims8
A metal salt complex of the formula ##STR6## wherein Y is a hydrogen atom or an unsubstituted alkyl group of 1 to 18 carbon atoms;
- R is hydrogen, halogen, or a (C.sub.1 -C.sub.4)alkyl group;
- R.sup.1 is hydrogen, halogen, or a (C.sub.1 -C.sub.4)alkyl group;
- or R and R' can be taken together to complete a benzene ring, optionally substituted with one or more halogen atoms, nitro groups, (C.sub.1 -C.sub.4)alkyl groups, cyano groups, or (C.sub.1 -C.sub.4)alkoxy groups;
- M is a cation of barium, cadmium, calcium, chromium cobalt, copper, iron, lead, lithium, magnesium, manganese, mercury, nickel, silver, sodium, strontium, tin, or zinc;
- X is a chloride, bromide, iodide, sulfate, nitrate, acetate, perchlorate, bisulfate, bicarbonate, oxalate, maleate, p-toluenesulfonate, carbonate, or phosphate anion;
- a is the integer 1 or 2;
- and
- n is the integer for which the anion X satisfies the valence of the cation M.
