A para-nitrophenyl functionalized C-3v symmetric flexible tripodal amide ligand, L, shows remarkable solvent dependent dual binding behaviour towards the octahedral hexafluorosilicate anion in solid state. In DMSO solvent the ligand encapsulates the hexafluorosilicate anion within its dimeric capsular assembly, whereas in the case of DMF solvent the ligand stabilizes the hexafluorosilicate anion via side cleft binding. The binding dissimilarities of the hexafluorosilicate anion in the complexes are also confirmed by Hirshfeld surface analysis.
