Аннотация:C14H18 (1), M(r) = 186.3, monoclinic, P2(1)/c, a = 9.285(6), b = 5.373(2), c = 11.981(6) angstrom, beta = 112.09(4)-degrees, V = 553.8(1) angstrom, Z = 2, D(x) = 1.12 g CM-3, lambda(Mo Kalpha) = 0.71073 angstrom, mu = 0.6 cm-1, F(000) = 204, T = 183 K, R = 0.050, wR = 0.049 for 871 observed reflections. The molecule occupies a special position at an inversion centre. The bond lengths in the three-membered ring are undisturbed due to the opposing influence of the double-bond pi-system conjugation with the Walsh molecular orbital of cyclopropane and strain due to a spiro conjunction of two small rings.
