In the present paper, in order to find the correlation between the mol. structure and the intermol. interaction patterns in the crystalline state and the corresponding gelating or nongelating behavior, two structurally related sets of copper complexes, including (CuCl2[L2pyTerpy]), 1, (CuCl2[L3pyTerpy]), 2, and (CuCl2[L4pyTerpy]), 3, (where LnpyTerpy is 4′-(n-pyridyl)-2,2′,6′,2”-terpyridine) as the first set and (CuCl2[L2pydipyz-py]), 4, (CuCl2[L3pydipyz-py]), 5, and (CuCl2[L4pydipyz-py]), 6, (where Lnpydipyz-py is 4-(n-pyridyl)-2,6-dipyrazin-2-yl-pyridine) as the second one, have been synthesized, and their crystal packing as well as gelating properties have been investigated. Results show that although these two sets are structurally similar the first set forms a metastable hydrogel, while the second one is unable to form a gel. To investigate the reasons, we employed Hirshfeld surface anal. and examined the differences in their packing arrangements, which suggest hydrogen bonding arranged into the three-dimensional network is a preferred mode of packing for the crystalline solid but is unfavorable for gel formation. In the part of experimental materials, we found many familiar compounds, such as 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3HPLC of Formula: 112881-51-3)
4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3) belongs to pyridine derivatives. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals. HPLC of Formula: 112881-51-3
