In the title polymer, [ZnCl(2)(C(11)H(8)N(2)O)](n), the Zn(II) atom lies on a twofold rotation axis and has a distorted tetra-hedral ZnCl(2)N(2) geometry involving two chloride donors and two N-atom donors from μ(2)-bridging bis-(pyridin-3-yl)methanone ligands, which also have twofold symmetry. A zigzag chain structure is formed, extending along (001). Each chain is surrounded by three others which are inter-connected through weak C=O⋯π(pyrid-yl) [O⋯centroid = 2.999 (3) Å] and π(pyrid-yl)-π(pyrid-yl) inter-actions [minimum ring centroid separation = 4.014 (2) Å], giving a three-dimensional framework.
