Authors:Ying Xu  Rui‐Hu Wang  Ben‐Yong Lou  Lei Han  Mao‐Chun Hong
Abstract:In the title compound, Fe(C5H3N2O4)2]n, each Fe atom lies on a centre of symmetry, in an octahedral coordination environment consisting of two chelate rings Fe—N = 2.154 (3) Å and Fe—O = 2.180 (3) Å] and two carboxyl­ate O atoms Fe—O = 2.111 (2) Å] from imidazole‐4,5‐di­carboxyl­ate ligands. Extensive hydrogen‐bonding interactions exist between layers constructed of Fe4 squares, forming tunnels along the a axis with large voids.
