Materials Data on RbCuO by Materials Project

RbCuO crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. Rb1+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. There are a spread of Rb–O bond distances ranging from 2.90–3.05 Å. Cu1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.84 Å. O2- is bonded to four equivalent Rb1+ and two equivalent Cu1+ atoms to form a mixture of distorted edge and corner-sharing ORb4Cu2 octahedra. The corner-sharing octahedra tilt angles range from 0–14°.

RbCuO结晶于四方晶系I-4m2空间群。该晶体结构为三维结构。Rb⁺以矩形跷跷板型配位几何与四个等价的O²⁻成键，Rb–O键长分布范围为2.90~3.05 Å。Cu⁺以直线型配位几何与两个等价的O²⁻成键，两处Cu–O键长均为1.84 Å。O²⁻与四个等价的Rb⁺和两个等价的Cu⁺成键，形成兼具畸变棱共用与角共用特征的ORb₄Cu₂型八面体配位单元。角共用八面体的倾斜角范围为0~14°。
