3-Azabicyclo[3.3.1]nonane-2,4-dione: CSP2001 structure prediction test case No. 1

R. A. Howie and J. M. S. Skakle

Abstract: Features of the structure of the title compound, C₈H₁₁NO₂, are the near planar arrangement of the dicarboximide fragment and the C atoms to it and the molecular non-crystallographic C_s mirror symmetry. N-HO hydrogen bonds link the molecules to form zigzag chains propagated in the a direction and sheets parallel to (001) are formed by replication of the chains by cell translation in the b direction. The sheets, related to one another by the operation of crystallographic centres of symmetry, are stacked in the c direction.
