BEISLER The National Institute of Arthritis and Metabolic Diseases AND J. V. SILVERTON The National Heart and Lung Institute, Bethesda, Maryland 20014, U.S.A. (Received 29 January 1971) Symmetrical cedrone, C1sH2006, obtained by dimerization of trimethylphloroglucinol has been shown to be a centrosymmetric pentacyclic structure in the crystal of its dimethylformamide solvate and has a considerable number of very long carbon--carbon bonds. Three independent bonds have lengths of 1"597 (3), 1-597 (3) and 1"577 (3) A. The molecule forms two, strong hydrogen bonds (2.668 A) to related molecules of the dimethylformamide solvate and is possibly stabilized by these bonds. There are two molecules of symmetrical cedrone and four molecules of dimethylformamide in the unit cell. Crystal data: monoclinic P21/c, a=9-322 (3), b=8.250 (2), c= 15.804 (4) A, ,8= 101"86 (3)°, Z =2, Dx= 1.335 g.cm-s, Dm= 1"34 (1)
