Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A metal salt complex having the structure ##SPC4## wherein R is a. hydrogen b. alkyl of 1 to 5 carbon atoms c. allyl d. CN e. CCl 3 and f. 5-tetrazolyl M is a metal cation, X is an anion forming a compound with the cation M in which the compound has sufficient solubility to form a metal salt complex, and a is an integer corresponding to the valence of cation M and n is an integer which for the anion X satisfied the valence of the cation M.
Claim 2
Dependent Claim
