In the title compound,catena-poly[[[N,N′-bis(pyridin-3-ylmethyl)-[1,1′-biphenyl]-4,4′-dicarboxamide]chloridozinc(II)]-μ-[1,1′-biphenyl]-4,4′-dicarboxylato-[[N,N′-bis(pyridin-3-ylmethyl)-[1,1′-biphenyl]-4,4′-dicarboxamide]chloridozinc(II)]-μ-[N,N′-bis(pyridin-3-ylmethyl)-[1,1′-biphenyl]-4,4′-dicarboxamide]], [Zn2(C14H8O4)Cl2(C26H22N4O2)3]n, the ZnIIcentre is four-coordinate and approximately tetrahedral, bonding to one carboxylate O atom from a bidentate bridging dianionic [1,1′-biphenyl]-4,4′-dicarboxylate ligand, to two pyridine N atoms from twoN,N′-bis(pyridin-3-ylmethyl)-[1,1′-biphenyl]-4,4′-dicarboxamide ligands and to one chloride ligand. The pyridyl ligands exhibit bidentate bridging and monodentate terminal coordination modes. The bidentate bridging pyridyl ligand and the bridging [1,1′-biphenyl]-4,4′-dicarboxylate ligand both lie on special positions, with inversion centres at the mid-points of their central C—C bonds. These bridging groups link the ZnIIcentres into a one-dimensional tape structure that propagates along the crystallographicbdirection. The tapes are interlinked into a two-dimensional layer in theabplane through N—H...O hydrogen bonds between the monodentate ligands. In addition, the thermal stability and solid-state photoluminescence properties of the title compound are reported.
