In recent years extended networks based on transition metal polypyridyl complexes have drawn increased attention due to their potential applications as requirement for the magnetic, electronic or photo­ optical materials for future use with molecular-scale electronic devices, for functions such as optical switches, fast recording devices and molecular computers
