Tin (IV) Iodide (CAS 7790-47-8) Applications

Tin (IV) Iodide (CAS 7790-47-8) has significant potential for application in the semiconductor industry due to its peculiar crystal structure.

The analysis of crystal structures of the synthesized Tin (IV) Iodide complexes shows the presence of π interactions along with hydrogen bonds (H···I). Due to the presence of only weak intermolecular interactions, SnI4 complexes are unique among the hybrid materials. Moreover, the composition of band structure highlights the importance of weak interactions in the solid-state: it causes the formation of the valence band mainly from the orbitals belonging to the inorganic core and the conduction band from the organic-ligand-centered orbitals. Also short I···I contacts were found to contribute significantly to the band structure of [SnI4(C5H5NO)2]. Their distances are smaller than those in the SnI4 crystal structure (4.206 Å).

The detailed studies presented above indicate the crucial role of intermolecular interactions in the design of novel semiconducting materials. The structural and physicochemical analysis helped to reveal a new and exciting family of molecular semiconductors based on main group elements. The main features of these materials are good solubility in common solvents (what enables, e.g., application of printing technologies to produce SnI4L2-based devices) and the possible tunability of properties. Tin (IV) Iodide offers an easily accessible platform for numerous semiconducting materials, as the variety of ligands it can accept is almost unlimited.
