Abstract
The X-ray molecular structures of bridgehead heterocycles, namely, 3-thia-1-azabicyclo[3.3.1]nonane-2-thione, 1,3-diazabicyclo[3.3.1]nonane-2-thione, (2Z)-2-(N-benzoylimino)-3-thia-1-azabicyclo[3.3.1]nonane and (2Z)-2-(3,4-dichlorophenylimino)-3-thia-1-azabicyclo[3.3.1]nonane were determined and their molecular packing in the crystals was revealed. The rings distortion in the bridgehead core was evaluated by the calculation of ZP and CP puckering parameters.
