Abstract

C17H2602, Mr=262, triclinic, PI, a=8.513 (2), b=8.970 (2), c=11.741 (3) Å, α=120.51 (5), β=93.30 (4), γ=68.43 (4)°, V =708.9, Å3, Z=2, DO=1.213, De=1.227 Mg m-3, μ(Mo Kα, λ=0.7107 Å)=0.084 mm-1, F(000)=288. The structure, solved by direct methods, has been refined to an R value of 5.9% using 1361 intensity measurements. The ring junctions, in sequence from either end of the polycycle, are cis, trans and cis.
