Abstract

The first alkaline-earth metal tin(II) phosphate, BaSn<sub>2</sub> (PO<sub>4</sub> )<sub>2</sub> , has been discovered, which consists of layered structures constructed from strictly alternating [SnO<sub>3</sub> ]<sup>4-</sup> and [PO<sub>4</sub> ]<sup>3-</sup> moieties. This compound is expected to have a large birefringence with Δn≈0.071 at 1064 nm, owing to the presence of stereochemically active lone pair metal cations.
