intermolecular O–H⋯O hydrogenbonding. This feature is also observed in isomer 2d but dimer pairs are further associated to give a 1-D chain through assisted intermolecular N–H⋯Cl hydrogenbonding. The additional 4-hydroxo group in 2e promotes a ladder arrangement via intermolecular O–H⋯O and O–H⋯Cl hydrogenbonding. In contrast the isomeric compound 2f does not show head-to-tail O–H⋯O hydrogenbonding but instead
