Volatile fluorinated trimethylplatinum(IV) β-diketonates with pyridine: Synthesis, properties, and structure

Volatile fluorinated trimethylplatinum(IV) beta-diketonates with pyridine (CH3)(3)Pt(CH3-CO-CH-CO-CF3)Py (I) and (CH3)(3)Pt(CF3-CO-CH-CO-CF3)Py (II) obtained from trifluoroacetylacetone and hexafluoroacetylacetone were studied. The synthesis, elemental analysis data, and IR spectra were described. X-Ray diffraction analysis was performed and the crystal structure was determined; the geometric characteristics of complexes I and II were obtained. Both structures are monomeric molecular structures. The molecules in the crystal are connected only by weak van der Waals forces. The coordination polyhedron of platinum in I and II is a slightly distorted octahedron. The shortest PtaEuro broken vertical bar Pt distances are 6.639 (for I) and 6.254 (for II). The average P-O, Pt-N, and P-C distances are 2.157, 2.182, and 2.030 , respectively. The deviations of the bond angles at Pt atoms from ideal values of 90A degrees do not exceed 4.8A degrees.
