“…Halometallates (III) organic-inorganic materials have generated significant interest because of their special structural features and high potential applications, such as electronic and optical materials [ 1 , 2 , 3 , 4 , 5 , 6 ]. Among these classes of materials, halogeno bismuthate(III) with general formula A a B b X 3b+a , where A = organic amine and X = I, Br, Cl, have emerged as an up-and-coming class of luminescent and semiconducting materials and have stimulated considerable interest among researchers [ 7 , 8 , 9 , 10 , 11 , 12 ]. The anion substructure of these materials comprises MX 6 octahedra that may be isolated (zero-dimensional—0D) or linked by edges, corners or faces (1D, 2D, 3D architectures) [ 13 , 14 , 15 ].…”
