Metal tetraphosphides (MP₄, M = 3d transition metals) exhibit the layered‐structure character, in which the metal atom chains are sandwiched between the P₄²⁻ layers, and have attracted considerable interest due to the outstanding physical and chemical properties, such as good electrical conductivity and high lithium capacity. Herein, the CrP₄ single crystal is prepared using the high‐pressure and high‐temperature method via the 2000 ton Kawai‐type multianvil apparatus at ShanghaiTech University (SHTech‐2000). The structural modification under high pressure is investigated by synchrotron X‐ray diffraction combined with diamond anvil cell techniques. CrP₄ shows remarkable axial anisotropic compressibility, in which the c‐axis is more compressible than a‐ and b‐axes. The formation of infinite chains of CrCr metallic bonding in CrP₄ under high pressure enhances the electrical conductivity.

非凡的各向异性压缩和金属Cr ？高压下拓扑半金属CrP4中的Cr链

四氯化金属（MP ₄，M = 3d过渡金属）具有层状结构特征，其中金属原子链夹在P ₄^2-层之间，由于其出色的物理和化学性质而引起了极大的兴趣，例如具有良好的导电性和高锂容量。此处，CrP ₄单晶是通过上海科技大学（SHTech-2000）的2000吨Kawai型多砧装置使用高压和高温方法制备的。通过同步加速器X射线衍射结合金刚石砧盒技术研究了高压下的结构改性。CrP ₄表现出显着的轴向各向异性可压缩性，其中c轴比a轴和b轴更具可压缩性。的Cr的无限链的形成的Cr金属接合在CRP ₄在高压下增强了导电性。
