Abstract
Inorganic chemistry attempts to understand the bridge between inorganic crystal structure and function. To fully understand function, the structure of a system must be first investigated and understood. Previous studies have investigated a Ba, P, S, and a Pb, P, S system and reported a change in the crystal structure. The Ba, P, S system had a centrosymmetric structure, while the Pb, P, S had a noncentrosymmetric structure. The difference in structure is due to the lone pair of electrons on the Pb atom that pushes the P, and S into a noncentrosymmetric structure. Here we report the discovery of a new Ba, Si, S system, and investigate how the replacement of P with Si affects the structure. In the future we anticipate to synthesize a Pb, Si, S system and investigate the effects Pb has on the system.
