通过温和水热反应得到的硒化铁不具有超导性，在60 K以下表现出三斜晶体结构，而传统固态合成的超导FeSe是正交的。相反，水热合成的四方硫化铁FeS具有超导性，但在冷却时没有发生结构变化。
Iron selenide obtained by mild hydrothermal reaction is not superconducting and exhibits a triclinic crystal structure below 60 K unlike superconducting FeSe from conventional solid state synthesis which is orthorhombic. In contrast, tetragonal iron sulphide FeS from hydrothermal synthesis is superconducting but undergoes no structural change on cooling.
