title: Bis[3-(2-carboxy-ethen-yl)pyridinium-1-acetato]dichloridozinc(II).
abstract: In the title complex, [ZnCl(2)(C(10)H(9)NO(4))(2)], the Zn(II) ion lies on a twofold rotation axis and is four-coordinated by two carboxyl-ate O atoms from two 3-(2-carboxy-ethen-yl)pyridinium-1-acetate ligands in a monodentate mode and two Cl atoms in a distorted tetra-hedral geometry. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into a double-chain structure extending parallel to [101].
