Popis:	Mr = 210.32, monoclinic, P21/a, a = 41.943(7), b = 6.410(2), c = 10.161 (3) A, β= 114.42 (2)°, V = 2487.4(11) A3, Z = 8, Dx = 1.12 gcm−3, MoKα, λ = 0.71069 A, μ = 0.79 cm−1, F (000) = 928, T = 291K, R = 0.058 for 2248 observed reflections. The trans configuration is observed. The two independent molecules of the asymmetric unit have a similar geometry with perfect chair and envelope conformations for respectively the 6- and 5-membered rings.
