The simplified (3,3,4,5)-connected topological network when Cu2, a CN− anion, Cu1 and a 4-ptz anion are regarded as 3-, 3-, 4- and 5-connected nodes, respectively. (In the electronic version of the paper, the cyan, grey and blue spheres represent the CuI cation, CN− anion and 4-ptz anion, respectively.) |
