No significant deviation from the rigid rotor approximation was observed and the conformation has $C_{2}$ symmetry (half chair conformation). The following are some of the more important structural $parameters:^{1}$ bond distances (A), $r(O{p}O_{p}) = 1.471 (0.009)$, $r(CO_{p}) = 1.397 (0.006)$, $r(CO_{p}) = 1.433 (0.009)$, $r (CH) = 1.094 (0.005)$; bond angles. \$
