Complex compounds of potassium or ammonium
trichloroammineplatinate(II) are used as starting mate-
rials in the synthesis of biologically active mixed plati-
num complexes of the second and third generations .
The synthesis of these complexes involves tetraam-
minedichloroplatinum(II) and potassium tetrachloro-
platinate(II) as subsidiary complexes, which are then
removed from the reaction in the form of the insoluble
Magnus salt [Pt
]. This salt is not
employed in subsequent synthesis of potassium or
ammonium trichloroammineplatinate(II), which sub-
stantially (by half) lowers the yields of the major prod-
This study was devoted to the synthesis of the iso-
mers of dichlorodiammineplatinum(II) from the Mag-
The Magnus salt [Pt
] was added to an
aqueous solution of ammonium acetate. The reaction
mixture was heated for an hour and then cooled. Hydro-
chloric acid was added and the resulting microcrystal-
line salt Pt
was isolated in 80% yield. Heat-
ing was continued for 1.5 h. On cooling,
] was isolated in 78% yield. The isomers
of dichlorodiammineplatinum(II) were identiﬁed, and
their structures were proven, by elemental and X-ray
diffraction analyses, IR spectroscopy, and UV spectro-
is used to prepare tet-
raamminedichloroplatinum(II), which is employed in
the synthesis of monoammineplatinum(II) compounds
. The salt
is used as a biologically
active substance  and as the starting reagent for the
synthesis of potassium or ammonium trichloroammine-
Thus, the proposed method provides substantial
increase in the yield of potassium or ammonium
trichloroammineplatinate(II) due to the use of platinum
from the Magnus salt.
