Abstract
The structure of a new phase of a volatile Pt(ktf)2 complex, where ktf = CF3–C(O)–CH–C(NH)–CH3, is determined by single crystal X-ray diffraction. The crystallographic data for C10H10F6N2O2Pt are as follows: a = 12.1716(7) Å, b = 8.5581(7) Å, c = 19.9966(15) Å, β = 96.840(3)°, space group P21/c, Z = 6, R = 0.046. The compound is a 2:1 mixture of cis- and trans-isomers. The square environment of the platinum atom consists of oxygen and nitrogen atoms of two bidentately bonded ketoiminate ligands, resulting in the PtO2N2 coordination core. The difference in Pt–O (2.005 Å) and Pt–N (1.990 Å) bond lengths is 0.015 Å in the trans-isomer; the O–Pt–N chelate angle is 93.6°. In the cis-isomer, the average Pt–O and Pt–N bond lengths are 2.002 Å and 1.967 Å respectively; the chelate angle is 94.8°. The molecules are packed into infinite stacks with Pt⋯Pt distances of 4.096 Å and 4.159 Å.
