“…In the cyclopropyl ring C15/C16/C20, the bond lengths C16-C20 and C15-C20 are different (1.524 (4) versus 1.484 (3) Å), which is also found in 3β-acetoxy-7α-chloro-5,6β-epoxy-15β,16β-methylene-5β-androstan-17-one (1.511 (5) and 1.473 (4) Å) reported previously (Zhou et al, 2007). The difference in these bond lengths might be caused by a hyperconjugation interacton between the C=O π-bonding and C16-C20 σ-bonding orbitals.…”
