The title compound, [Zn(C8H6N4O3)]n or [Zn(L)]n [H2L is 3‐(6‐oxo‐6,9‐dihydro‐1H‐purin‐1‐yl)propionic acid], crystallized as a nonmerohedral twin. The ZnII cation is four‐coordinated, ligated by two carboxylate O atoms from two L ligands and two N atoms from another two ligands. Each ligand bridges four ZnII centres, extending the structure into a three‐dimensional polymer with a 4‐connected (65,41) topological structure containing two‐dimensional homochiral layers constructed from one‐dimensional metal–organic helices. Investigation of the thermal stability of the compound shows that the network has very high thermostability and is stable up to 720 K.
