New supramolecular architectures of 4′-(4-quinolinyl)-2,2′:6′,2″-terpyridine based on tin complexes: Design, structural variations and thermal properties

•New complexes of Sn(II) and Sn(II) based on the 4′-substituted terpyridine ligand.•Supramolecular assembly of tin compounds through noncovalent interactions.•Hirshfeld surface analysis was used to analyze the intermolecular interaction.•The formation of porous tin material containing voids occupied by the solvents.•Thermal properties of the complexes were investigated.
