Materials Data on ErV2O2 by Materials Project

ErV2O2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Er is bonded in a linear geometry to two equivalent O atoms. Both Er–O bond lengths are 2.15 Å. V is bonded in a 1-coordinate geometry to three equivalent O atoms. There are one shorter (2.04 Å) and two longer (2.27 Å) V–O bond lengths. O is bonded in a rectangular see-saw-like geometry to one Er and three equivalent V atoms.ErV₂O₂ 以四方晶系I4₁/amd空间群结晶，其晶体结构为三维结构。铒（Er）原子以线性配位几何与两个等价的氧（O）原子成键，二者的Er-O键长均为2.15埃。钒（V）原子以单配位几何与三个等价的氧（O）原子成键，其中存在一条键长为2.04埃的较短V-O键与两条键长为2.27埃的较长V-O键。氧（O）原子以矩形跷跷板状配位几何与一个铒（Er）原子及三个等价的钒（V）原子成键。
