Concomitant crystallization of supramolecular isomers: ۲-foldinterpenetrated and non-intenterpenetrated coordination polymers

Coordination polymers (CPs) have been undergoing rapid development due to their facilefunctionalization [۱], diverse topologies [۲] and varied potential applications [۳,۴].Supramolecular isomerism is used to describe the existence of more than one type ofsupramolecular network for a given set of components. To the best of our knowledge, research onthe concomitant formation of supramolecular isomers is still rare [۵]. In this work, we report theone-pot synthesis of two CPs, namely {[Cd(L)۱.۵(NO۳)۲](L) ۰.۵}n (۱) and [Cd(L)۱.۵(NO۳)۲]n (۲), bythe self-assembly process using cadmium (II) ion as metallic tectons and pyridine containingligand (L) as organic tectons in EtOH. These compounds were structurally characterized by singlecrystalX-ray diffraction analysis and further characterized by powder X-ray diffraction (PXRD).As illustrated in Fig. ۱, compound ۱ can be considered as ۲-fold interpenetrated framework, whilecompound ۲ is a non-intenterpenetrated coordination polymer. Hirshfeld surface analysis of thecompounds ۱ and ۲ have been performed to investigate the relative contributions of eachinteraction in crystal packing
