24. Figure I shows no unusual motion of the atoms perpendicular to the molecular plane; however, atoms C(7), C(8), C(15), and C(16) show a tendency to move in a direction along the bond. This is somewhat unusual and probably suggests that the empirical absorption correction applied to this plate-shaped crystal is not ideal. A reexamination of these displacement parameters and the refinement process revealed no other systematic problems.
