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).
