crystallization from racemic solutions were found here. The crystal structures were firstly subjected to Hirshfeld surfaces analysis. The development of hydrogen bonding driven two-dimensional assemblies such as tapes, ribbons and sheets was further analysed using DFT calculations in terms of contribution of dimeric motifs as building blocks, which are associated with the presence of intermolecular interactions
