  • Crystal data for (4) C18H30O2; a = 6.388(2), b = 6.398(2), c = 11.439(2) å, α = 97.89, β = 99.43, γ = 114.19, triclinic, space group P 1, Z = 1 F (000) = 154, Dx = 1.128 mg. m−3, λ (Cu-Kα) = 1.54178 Δ° μ(Cu-Kα) = 5.48 cm−1, T° = 296 K. Data were collected on a Nicolet P3/F diffractometer with Ni-filter monochromatized Cu-Kα radiation. The structure was solved by direct methods (SIR92, Altomare A. Appl. Cryst. 1994 27 435) and refined by full matrix least-square procedure using SHELXTL (Seldrick, G. M. SHELXTL. PC User Manual Siemens Analytical X-Ray instruments, Madisson, Wisconsin, U.S.A. 1990). In the final cycles of refinement all non-hydrogen atoms were treated anisotropically. The hydrogen atoms attached to carbon atoms were included as fixed contributions, the function minimized was Σω (|F0| - |Fc|)2, where ω−1 = σ2 (F) + 0.0008 F0 2 resulting in R = 0.062, Rw = 0.068 and S = 1.43.
