Abstract

The title compound crystallizes in the monoclinic space group P2₁/n, with a = 6.225(1), b = 14.612 (1), c = 15.520 (1) Å, β = 96.6(3)°, Z = 4 and V = 1402.4Å³. The stereochemistry of the 7/5-fused ring system is trans, the 7-membered and the 5-membered rings are found to be in the chair and envelope conformations, respectively. This represents the first study of a compound containing the 7/5-ring skeleton shown in (3) below.
