The structures of two Al(III) and Fe(III) β-diketonates with a γ-substituted ligand are studied by single crystal X-ray diffraction at 150(2) K. Crystallographic data for Al(γ-Me-hd)3 (I) are: space group \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$P\bar{1}$$\end{document}, a = 10.855(1) Å, b = 11.129(1) Å, с = 11.894(1) Å, α = 85.634(3)°, F0200062 = 73.118(3)°, γ = 66.771(3)°, V = 1262.2(2) Å3, Z = 2, R1 = 0.0438. For Fe(γ-Me-hd)3 (II): space group P21/с, a = 10.0374(5) Å, b = 17.0798(7) Å, с = 15.7213(6) Å, F0200062 = 107.459(1)°, V = 2571.1(2) Å3, Z = 4, R1 = 0.0364. Compounds I and II are isotypical because their molecules have the same structure but crystallize in different crystal systems. The crystal structures of I and II are molecular and consist of discrete M(γ-Me-hd)3 (M = Al, Fe) molecules. Thermogravimetric studies show that complexes I and II are similarly volatile. For Cu(γ-Me-hd)2 complex (III) the saturated vapor pressure is measured by the Knudsen method in the temperature range 100-150 °C. Sublimation thermodynamic parameters are found and vapor thermolysis is investigated.
