Phase relations in the pseudobinary systems RAO3-R2Ti2O7 (R: rare earth element and Y, A: Fe, Ga, Al, Cr and Mn) and syntheses of new compounds R(A1−xTix)O3+x/2 (2/3≤x≤3/4) at elevated temperatures in air

The crystal structure of InGaO3 (rhombic, hypothetical) is fundamental for understanding the crystal structures of the monoclinic In(A1−xTix)O3+x/2 and the rhombic R(A1−xTix)O3+x/2, which have both cations A and Ti with CN=5.198
