Abstract
The single crystal X-ray diffraction (XRD) method was used to determine the structure of the [Cu(mi-tfac)(2)] (mi-tfac = MeC(O)CHC(NMe)CF3) complex at the temperature of 150 K. The crystallographic data are as follows: space group Pnna, a = 11.8798(16) , b = 12.0315(16) , c = 10.6259(14) , V = 1518.8(4) (3), Z = 4, R = 0.0288. The structure is molecular, the coordination environment of copper in the molecule adopts a distorted tetrahedral geometry. The Cu-O and Cu-N distances are 1.9182(13) and 1.9610(16) respectively, the OCuN chelate angle is 94.18(5)A degrees. The thermal properties of the compounds [Cu(mi-tfac)(2)] and [Cu(RC(O)CHC(NMe)R)(2)] (R = Me, (t) Bu) in the condensed phase have been studied by the methods of thermogravimetry and differential scanning calorimetry. The thermodynamic characteristics of the melting processes have been determined.
