We report the synthesis of a new series of layered copper oxide compounds, Nd2-x-yAxCeyCuO4-δ (AgII Mg and Ca), which are isostructural with the T′-phase of the superconducting, n-type Nd2-xCexCuO4-δ. An extended solid solubility range, x + y ≤ 0.60, is observed. The as-prepared air-quenched samples show semiconducting behavior. These newly prepared compounds raise further questions about electron-doped superconductivity in the cuprate oxides.
