Crystal structure of KTi0.93Sn0.07OPO4

To reveal correlations between the atomic structure and properties of the K Ti1-xSnxOPO4 solid solutions, single crystals of the KTi0.93Sn0.07OPO4 comp osition were synthesized and their structure was determined. The crystals b elong to the KTiOPO4 family; orthorhombic, sp. gr. Pna2(1). The unit-cell p arameters are a = 12.831, b = 6.410, and c = 10.584 Angstrom. The partial s ubstitution of Sn atoms for Ti atoms results in the formation of more symme tric coordination polyhedra in the structure framework and the change of th e physical properties of the crystals.
