Differential thermal analysis coupled to temperature-controlled diffraction have given evidence of a topological metastability phenomenon in an extended compositional range of the La2xNdxMo2O9 solid solution. A metastable–stable phase diagram is proposed for this series of LAMOX-type fast oxide-ion conductors. In the Nd range 0
