摘要：

The structure of KTiO(P0.5As0.5)O4 has been determined by time-of-flight neutron diffraction: Pn2(1)a, a = 12.9695(8) angstrom, b = 10.6898(7) angstrom, c = 6.4932(4) angstrom, V = 900.2(2) angstrom 3, R(p) = 2.88, (w)R(p) = 4.23. The arsenic atoms enter the phosphorous sites in a random fashion. Powder second-harmonic generation (SHG) data reveal a correlation between the Ti(1)-O(9)-Ti(2) bond angle and the non-linear optical (NLO) coefficient in teh KTiOP1-xAsxO4 system.
