A new layered pnictide oxide (Fe 2 P 2 )(Sr 4 Sc 2 O 6 ) has been synthesized by solid-state reaction. This material has an alternating layer stacking structure of anti-fluorite Fe 2 P 2 and perovskite-based Sr 4 Sc 2 O 6 oxide layers. The space group of the material is P 4/ nmm and the lattice constants a and c are 4.016 and 15.543 Å, respectively. The interlayer Fe–Fe distance corresponding to the c -axis length is the longest ever reported in the iron-based pnictides. In both magnetization and resistivity measurements, the present compound exhibited superconductivity below 17 K; this temperature is much higher than that for LaFePO and the highest in arsenic-free iron-based pnictide systems under ambient pressure.
