Abstract: 2,5-Bis[4-methyl-3-(pyridin-3-yl)phen­yl]-1,3,4-oxa­diazole (L), C26H20N4O, forms one-dimensional chains via two types of inter­molecular [pi]-[pi] inter­actions. In catena-poly[[di­chlorido­zinc(II)]-[mu]-2,5-bis­[4-methyl-3-(pyridin-3-yl)phen­yl]-1,3,4-oxa­diazole], [ZnCl2(C26H20N4O)]n, synthesized by the com­bination of L with ZnCl2, the ZnII centres are coordinated by two Cl atoms and two N atoms from two L ligands. [ZnCl2L]n forms one-dimensional P (plus) and M (minus) helical chains, where the L ligand has different directions of twist. The helical chains stack together via inter­chain [pi]-[pi] and C-H...[pi] inter­actions.

Formula: C26H20N4O and [ZnCl2(C26H20N4O)]

Keywords: crystal structure; MOFs; coordination polymers; helical chains.
