Topological analysis of intermolecular interactions
The intermolecular interactions present in the title complex were quantitatively analyzed using topological parameters. These parameters for the intermolecular interactions at the BCPs are summarized in Table 3 and the molecular graphs of various dimeric motifs are depicted in the supporting information (Fig. S1). The molecular graphs In the title complex, six intermolecular N–H···O hydrogen bonding interactions are observed in which three of them are N–H+···O- type HB (involving protonated side chain/backbone N atoms and deprotonated carboxylate groups of lysine and mandelate) and the remaining three of them are N–H+···O type HB (involving oxygens of water and hydroxy groups).
