Creators
Description
The reaction between acid ammonium mono-oxalatomolybdate and complex cobalt cations in aqueous solution gage products of the general formula, R(NH4), [MoO3(C2O4)] xH2O where R is a complex cation like [Co(BigH+)3 ]3+ [CoEn3]3+ [Co(NH3)6]; BigH=C2N5H2 one molecule of biguanide; En=C2N2H8, one molecule of ethylenediaminel x, y, and z are certain specified integral numbers. In the case of cobaltic trisbiguanide compound y=o, and hence only one type (normal) of salt was obtained. The composition and dehydration of these compounds furnish evidences regarding the stability of the anionic complex monooxalatomolybdate in aqueous solution.
