Abstract: A new layered oxypnictide Fe2P2Sr4Sc2O6 have been synthesized bysolid-state reaction. This material has an alternating layer stacking structureof anti-fluorite Fe2P2 and perovskite-based Sr4Sc2O6 oxide layers. Space groupof the material is P4-nmm and lattice constants a and c are 4.016 A and 15.543A, respectively. The interlayer Fe-Fe distance corresponding to the c-axislength is the longest ever reported in the iron-based oxypnictide systems. Inboth magnetization and resistivity measurements, the present compound exhibitedsuperconductivity below 17 K, which is much higher than that of LaFePO and thehighest in arsenic-free iron-based oxypnictide systems under ambient pressure.
