The invention relates to a process for the treatment of tumors in animals with water soluble square-planar cis platinum(II) four-coordinate complexes comprising different nonovalent and divalent organic cations. Monovalent cations include galacturonato and N,N-dimethylglycinato and divalent cations include citraconato, 1,1-cyclobutanedicarboxylato, 1,1-cyclopropanedicarboxylato and Z-iminodiacetato where Z is bound to the nitrogen and is ethyl, propyl, isopropyl, n-butyl, secbutyl, ter-butyl, n-amyl, isoamyl or -OH. The treatment of animals comprises administering to the animals a pharmaceutical composition comprising a platinum complex of the composition described.
