C20H15Cl, M(r) = 290.8, monoclinic, P2(1)/c, a = 20.449 (4), b = 11.473 (2), c = 13.025 (2) A, beta = 108.91 (1)degree, V = 2890.9 A, Z = 8, Dx = 1.336 g cm-3, lambda (Cu K alpha) = 1.5418 A, mu = 21.14 cm-1, F(000) = 1216, T = 294 K, R = 0.045, wR = 0.049, for 3471 diffractometer data [Io > or = 3 sigma (I)]. The ring system is puckered as a result of the bulkiness of the 12-methyl group.
C20H15Cl，相对分子质量M(r)=290.8，单斜晶系，P2(1)/c，a = 20.449(4)，b = 11.473(2)，c = 13.025(2)埃，β = 108.91(1)°，V = 2890.9埃³，Z = 8，晶体密度Dx = 1.336克/厘米³，λ(Cu Kα)= 1.5418埃，线性吸收系数μ = 21.14厘米⁻¹，F(000)= 1216，温度T = 294 K，对于3471个衍射仪数据[Io≥3σ(I)]，R = 0.045，wR = 0.049。由于12 - 甲基的庞大体积，环系呈褶皱状。
