Abstract

Crystals of two alkali‐metal tin(IV) arsenates, KSnOAsO4 and RbSnOAsO4, were grown from a flux and structurally characterized by single‐crystal X‐ray diffraction. Crystal data: RSnOAsO4, orthorhombic, Pna21 (No. 33), a = 13.406(3) Å, b = 6.678(1) Å, c = 10.921(2) Å, Z = 8, R = 0.037 for 1173 independent reflections with I > 2.5ó(l); RbSnOAsO4, as above except a = 13.567(3) Å, b = 6.791( 1) Å, c = 10.891(2) Å, R = 0.035 for 1958 independent reflections. The two compounds are isostructural with the nonlinear optical material KTiOPO4. The oxygen frameworks of both tin compounds approximate closely to a centrosymmetric arrangement, as indicated from the analysis of atomic coordinates. Second harmonics were generated in powdered RbSnOAsO4 to confirm the absence of a center of symmetry in the structure.
