A series of new compoundsRAO3(MO)n(n= 1–11) having spinel, YbFe2O4, or InFeO3(ZnO)ntypes of structures were newly synthesized (R=Sc, In, Y, Lu, Yb, Tm, or Er;A=Fe(III), Ga, Cr, or Al;M=Mg, Mn, Fe(II), Co, Ni, Zn, or Cd) at elevated temperatures. The conditions of synthesis and the lattice constants for these compounds are reported. The stacking sequences of the InO1.5, (FeZn)O2.5, and ZnO layers for InFeO3(ZnO)10and the TmO1.5, (AlZn)O2.5, and ZnO layers for TmAlO3(ZnO)11are presented, respectively. The crystal structures of the(RAO3)m(MO)nphases (R=Sc, In, Y, or lanthanide elements;A=Fe(III), Ga, Cr, or Al;M=divalent cation elements;mandn=integer) are classified into four crystal structure types (K2NiF4, CaFe2O4, YbFe2O4, and spinel), based upon the constituent cationsR, A, andM
