| Summary: | In the title metal–organic polymeric complex, [CuI(C5H5N3O)]n, the asymmetric unit is composed of one monomer unit of the polymer and one CuI atom linked to one iodide anion and one pyrazine-2-carboxamide molecule. The CuI atom is in a distorted tetrahedral coordination completed by one pyrazine N atom of the pyrazine-2-carboxamide ligand and three iodide anions. The polymeric structure adopts a well-known ladder-like motif of {CuNI3} tetrahedra running in the b-axis direction. The molecules of the organic ligand are connected via medium-to-strong N—H...O and N—H...N hydrogen bonds and weak π–π interactions [the distance between two parallel planes of the rings is 3.5476 (14) Å and the centroid–centroid contact is 4.080 (2) Å]. The title compound has a relatively high decomposition temperature (564 K) as a result of relatively strong covalent and non-covalent interactions inside and between the chains. |
