In the work, isomeric complexes of platinum(II) with the (ptac)–1 pivaloyltrifluoroacetonate ion (Pt((CH3)3–CO–CH–CO–CF3)2) are studied. The synthesis and chromatographic separation of Pt(ptac)2 isomers are described, TGA data for the separated isomers are given, and the crystal structures of the solid phases are studied. The cis-Pt(ptac)2 complex crystallizes in the space group P-1, a = 10.7091(4) ?, b = 12.7787(6) ?, c = 16.0154(8) ?, α = 92.389(2)°, β = 90.868(2)°, γ = 112.1260(10)°, V = 2027.39(16) ?3, Z = 4, dcalc = 1.918 g/cm3. The trans-Pt(ptac)2 complex crystallizes in the space group C2/m, a = 13.3235(5) ?, b = 8.5515(3) ?, c = 9.6694(3) ?, β = 118.5880(10)°, V = 967.38(6) ?3, Z = 2, dcalc = 2.010 g/cm3. The structures of the complexes are molecular, the Pt atom has a square coordination of four oxygen atoms of two ligands; for cis-Pt(ptac)2, the Pt–Oav distance is 1.968 ?, for trans-Pt(ptac)2 it is 1.980 ?.
