文摘
- •
Compound 1, which crystalizes in P21, present Z' = 4 as result of packing forces.
- •
Compound 2 crystalizes with Z' = 0.5 because part of its molecular backbone lies in the Pnma mirror plane.
- •
Compounds 3 and 4, which crystalize in P21/c, present with Z' = 2 as result of conformerism.
- •
The conformation of benzyl moiety is responsible for the non-centrosymmetric space group of 1.
- •
The crystal packing of the compounds is marked by double catemer motif.
