Structural, spectroscopic, transport, and magnetic results are presented for Nd2-xAx4+CuO4- materials with A=Ce and Th. The structural and spectroscopic results indicate a continuous evolution in properties up to the stability limit of x=0.2. In dramatic contrast, the superconducting properties are sharply peaked near x=0.16 where the system crosses over from semiconducting to metallic-type behavior.
