采用传统的固相法合成了LiCu2、P2和LiFeP。LiCu(2)P(2)具有与BaFe(2)As(2)相似的晶体结构；LiFeP具有与LiVAS相同的晶体结构。电阻率和磁化强度测量表明，LiCu2和LiFeP分别在3.5K和4.1K时超导。
LiCu(2)P(2) and LiFeP have been synthesized by conventional solid-state reaction. LiCu(2)P(2) has a crystal structure similar to that of BaFe(2)As(2); LiFeP has the same crystal structure as that of LiFeAs. Resistivity and magnetization measurements reveal that they become superconductive at 3.5 K for LiCu(2)P(2) and 4.1 K for LiFeP.
