The title compound 2-(4-ethoxybenzoyl)cyclopentane-1,3-dione(C14H14O4) was synthesized, and its crystal structure was studied. It crystallized in the triclinic system, space group P1 with a = 8.980(2), b = 9.080(2), c = 15.482(3) , α = 93.49(3), β = 93.84(3), γ = 107.27(3)°, Dc = 1.365 g/cm3, Z = 4, λ = 0.71073, μ(MoKα) = 2.769 mm-1, Mr = 246.25, V = 1198.5(4)3, F(000) = 520, the final R = 0.0559 and wR = 0.1278 for 2301 observed reflections with I > 2σ(I). In the crystalline state, the molecular skeleton contains one enol grouping, which is intramolecularly hydrogen bonded to a neighboring keto O atom. Preliminary bioassay result showed that this compound provided 93.8% and 87.2% control of B. campestris and A. retroflexus at post-emergence at 375 g/hm2.
