Morozova, P. Stabnikov, I. Baidina, P. Semyannikov, S. Trubin, I. Igumenov] Copper(II) chelates with β-diimine derivatives of acetylacetone that have a general formula of Cu(R1C(NR2)CHC(NR2)R1)2, where R1, R2 are alkyl substituents, are synthesized. The complexes were identified using elemental analysis, melting point measurements, and high-temperature mass spectrometry data. Knudsen technique is employed to determine the vapor pressure temperature dependence, and standard thermodynamic parameters of sublimation ΔH T 0 and ΔS T 0 are derived. A single crystal X-ray diffraction study is carried out for copper(II) complexes of Cu(CH3-C(NCH3)-CH-C(NCH3)-CH3)2 (a = 10.363(1) Å, b = 11.978(1) Å, c = 12.653(1) Å, V = 1570.6(3) Å3, space group Pnc2, Z = 4, d calc = 1.328 g/cm3, R = 0.027), Cu(CH3-C(NC2H5)-CH-C(NC2H5)-CH3)2 (a = 11.782(4) Å, b = 13.951(8) Å, c = 25.591(8) Å, V = 4206(3) Å3, space group C2221, Z = 8, d calc = 1.169 g/cm3, R = 0.10), and also 2-(methylamino)-4-(methylimino)-pentene-2 CH3-(C=(NCH3))-CH=(C-(NHCH3))-CH3 (a = 12.129(2) Å, b = 12.034(2) Å, c = 5.692(1) Å, β = 107.05(3)°, V = 794.3(3) Å3, space group Cc, Z = 4, d calc = 1.055 g/cm3, R = 0.06). Van der Waals lattice energy E cryst is calculated for the cooper(II) complexes by the atom-atom potential technique. The calculated values are compared to experimental sublimation enthalpies Δ H T 0 .
