Abstract:
The present study reports the synthesis, crystal structure, and electronic properties of the lead-oxide-iodide-carbodiimde Pb8O4I6(CN2). The n-type semiconducting compound was obtained via ceramic method from PbI2, PbO and Pb(CN2), yielding an air stable, dark yellow crystalline material. Single-crystal X-ray diffraction revealed the monoclinic space group C2/c featuring a heterocubane-type [Pb4O4] motif interconnected by iodide bridges and (NCN)2- units. The optical properties were characterized by diffuse reflectance UV-Vis spectroscopy, Mott-Schottky analysis, and photoluminescence spectroscopy, providing insights into the electronic structure.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
