Copper amino acidate diimine nitrate compounds of the formula [Cu(N-N)(N-O)]+NO3-, where (N-N) is a diimine selected from 1,10-phenanthroline or 4,7-dimethyl 1,10-phenanthroline and (N-O) is tyrosine-alaninate, threoninate, tryptophanate, valinate, isoleucinate, cysteinate, diglycinate, phenylalaninate, glycinate, histidinate, serinate, tryosinate, aspartate or alaninate and a process for preparing the compounds in which, while maintaining a pH between 5 and 7, a first aqueous solution of Cu(NO3)2.5H2O, having 30 to 35% by weight of elemental copper, is reacted with a second aqueous solution of the diimine having a ratio of 50 to 55% by weight diimine to solution to form a monodiimine nitrate as an intermediate reaction product having the formula [Cu(N-N)(H2O)2]+NO3- and then reacting the intermediate product with a third aqueous solution containing 10 to 15% by weight of an amino acid, while keeping an alkaline pH between 7 and 8, with an aqueous ammonical solution to obtain the copper compound.
