Abstract. Tris(acetylacetonato)gallium(III), C1sH2106Ga, M.W. 367.05, monoclinic, P21/c, a= 14.003 (4), b=7.588 (2), c=16-491 (3) A, fl= 99.00 (2)°; U= 1720.2 (7) A3; dramas = 1-41, dealt = 1"417 g cm -3 for Z=4; p(Cu Kc0=25"7 cm-k The compound was prepared by the reaction of GaCI3 with sodium acetylacetonate. Large, plate-like, orange crystals were grown from methanol. The final R was 0.060 for 1872 observed reflections used in the analysis. The 6 oxygen atoms of the three ligands form a nearly ideal octahedron around the gallium atom. The average Ga-O bond length is 1.952 (6) A, with an average ligand bite of 2.802 A.
