Materials Data on U2Ru by Materials Project

U2Ru crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two U2Ru sheets oriented in the (1, 0, 0) direction. there are three inequivalent U sites. In the first U site, U is bonded in a distorted rectangular see-saw-like geometry to four U and four equivalent Ru atoms. There are a spread of U–U bond distances ranging from 3.09–3.18 Å. There are two shorter (2.73 Å) and two longer (2.75 Å) U–Ru bond lengths. In the second U site, U is bonded to eight U and four equivalent Ru atoms to form a mixture of distorted corner and face-sharing UU8Ru4 cuboctahedra. All U–U bond lengths are 2.73 Å. There are two shorter (3.21 Å) and two longer (3.31 Å) U–Ru bond lengths. In the third U site, U is bonded to eight U and four equivalent Ru atoms to form a mixture of distorted corner and face-sharing UU8Ru4 cuboctahedra. All U–Ru bond lengths are 3.27 Å. Ru is bonded in a distorted rectangular see-saw-like geometry to eight U atoms.

U₂Ru以单斜晶系（monoclinic）C2/m空间群（space group）结晶。该结构为二维结构，包含两片沿(1, 0, 0)晶向排布的U₂Ru层片。体系中存在三个不等价的铀（U）配位位点。在第一个铀位点中，U原子以畸变矩形跷跷板型配位几何（distorted rectangular see-saw-like geometry）与4个U原子及4个等价的钌（Ru）原子成键；U-U键长分布在3.09~3.18 Å之间，U-Ru键长分为两组，两组较短键长为2.73 Å，两组较长键长为2.75 Å。在第二个铀位点中，U原子与8个U原子及4个等价的Ru原子成键，形成兼具畸变共角与共面（corner and face-sharing）特征的UU₈Ru₄立方八面体（cuboctahedra）配位构型；该位点的所有U-U键长均为2.73 Å，U-Ru键长分为两组，两组较短键长为3.21 Å，两组较长键长为3.31 Å。在第三个铀位点中，U原子与8个U原子及4个等价的Ru原子成键，同样形成兼具畸变共角与共面特征的UU₈Ru₄立方八面体配位构型，该位点的所有U-Ru键长均为3.27 Å。Ru原子以畸变矩形跷跷板型配位几何与8个U原子成键。
