Sb2TeO7: A Chiral Antimony Tellurite with Phase-Matchable Second-Harmonic Generation
Noncentrosymmetric (NCS) structures are uncommon among compositionally simple inorganic solids, even when their constituent polyhedra are locally asymmetric. Here, we establish the binary tellurite Sb2TeO7 as a chiral NCS crystal that adopts the orthorhombic space group P212121 (No. 19). Stereochemically active trigo...
