The Structure of Triketones in the Solid-State. The Crystal-Structure of 1,5-Diphenylpentane-1,3,5-Trione

Abstract

The crystal structure of 1,5-diphenylpentane-1,3,5-trione was determined, C₁₇F₁₄O₃, M266.14, orthorhombic, space group Pbca , a 8.602(2), b 10.398(2), c 30.010(10) Å, V 2684 14 ų, p(ca1c) 1.317g cm^-3, Z 8, F(000) 1120, µ(Cu Ka) 6.91 cm^-l. The structure was solved by direct methods and refined to a final R value of 0.040 for 1539 unique reflections. The molecules of the compound are found in the dienol form.
