C₁₂H₁₄O₂, M_r = 190.24, orthorhombic, Pca2₁, a = 6.931 (2), b = 7.708 (2), c = 20.288 (4) A, V = 1084 A3, Z = 4, D_x = 1.17 g cm^-3, λ(Mo Kα) = 0.71069 A, μ = 0.73cm^-1. F(000) = 408, T = 298 K, R = 0.078 for 398 unique reflections. The ester substituent also adopts a cis-bisected conformation with the carbonyl oxygen eclipsing the ring. The phenyl substituent also adopts the bisected conformation and, hence, competes with the ester group in conjugative interactions with the cyclopropane ring. Ring bond lengths are equal at 1.50 (2), 1.51 (2) A, the high e.s.d.’s being due to limitations placed on the room - temperature data set by the low melting point (311 - 312 K).
