Abstract
The structure of (CH3)3Pt(ptac)Py (ptac = (CH3)3C(O)CHC(O)CF3) is determined by single crystal X-ray diffraction at a temperature of 150 K. The crystallographic data are: space group P 21/ c , a = 8.5513(2) Å, b = 16.1089(3) Å, c = 14,0877(3) Å, b = 107.4060(10)°, V = 1851.75(7) Å3, Z = 4, R = 0.0365. The structure is of the molecular type; the coordination environment of platinum in the molecule is distorted octahedral. The average Pt-O and Pt-CMe distances are 2.149(1) Å and 2.029(5) Å respectively, Pt-N 2.179(2) Å; the chelate angle O-Pt-O = 89.77(8)°. By thermogravimetry the thermal properties of (CH3)3Pt(ptac)Py are studied in the condensed phase.
