Abstract
The crystal structure of 1-hydroxy-2,3-dicarbomethoxy-1,3-cycloheptadiene has been determined from three-dimensional counter data, and refined by full-matrix least-squares techniques. The crystals belong to the triclinic space groupP¯1, witha = 10.721(7),b = 8.628(6),c = 6.214(6) Å, α = 91.65(5), β = 83.14(5), γ = 81.66(5) °, andD c = 1.33 g cm−3 forZ = 2. The finalR factor for 1385 observed reflections is 0.058. The compound exists in the enolic configuration.
