An alternative to ‘propylene/Leonard linker’ for studying arene interactions in flexible pyrazolo[3,4-d]pyrimidine core based models both at molecular and supramolecular levels

Studies on arene interactions in flexible pyrazolo[3,4-d]pyrimidine core based symmetrical ‘propylene/Leonard linker’ models: X-ray crystallographic evidence for disappearance of intramolecular stacking due to presence of chloro- or cyano-groups in place of methylsulfanyl or alkoxy substituents
