“…Owing to their high electronegativity and spectroscopic features, the cyanide group (CN – ) can combine with the transition-metal results in producing large diversity complexes with a great variety of coordination modes. − Moreover, PB exhibits a special structure anchored to the extended porosity and transfer of charge carriers from cyanide bridge CN through nitrogen or carbon atom to a metal center creating 1D, 2D, and 3D nanomaterials with open frameworks. , Despite the aforementioned advantages, the PBAs have some drawbacks such as low conductivity and molecular aggregation. To optimize their performance and avoid these problems, conductive nanoparticles including carbon nanotubes (CNTs) or graphene could be combined with the PB framework. , Moreover, a change in the transition metal that linked nitrogen molecules to manganese (Mn), zinc (Zn), iridium (Ir), ruthenium (Ru), cadmium (Cd), copper (Cu), cobalt (Co), chromium (Cr), and palladium (Pd) creates novel complexes with excellent structural, optical, magnetic, and electrical properties. − …”
