A new iron pnictide LiFeP superconductor was found. The compound crystallizes into a Cu2Sb structure containing an “FeP” layer showing superconductivity with maximum Tc of 6 K. This is the first “111” type iron pnictide superconductor containing no arsenic. The new superconductor is featured with itinerant behavior at normal state that could be helpful to understand the novel superconducting mechanism of iron pnictide compounds.
