The synthesis of the first 4d transition metal oxide–hydride, LaSr3NiRuO4H4, is prepared via topochemical anion exchange. Neutron diffraction data show that the hydride ions occupy the equatorial anion sites in the host lattice and as a result the Ru and Ni cations are located in a plane containing only hydride ligands, a unique structural feature with obvious parallels to the CuO2 sheets present in the superconducting cuprates. DFT calculations confirm the presence of S=
Ni+ and S=0, Ru2+ centers, but neutron diffraction and μSR data show no evidence for long‐range magnetic order between the Ni centers down to 1.8 K. The observed weak inter‐cation magnetic coupling can be attributed to poor overlap between Ni 3d
and H 1s in the super‐exchange pathways.

LaSr3NiRuO4H4：含金属氢化物薄板的4d过渡金属氧化物-氢化物
通过拓扑化学阴离子交换制备了第一种4d过渡金属氧化物氢化物LaSr 3 NiRuO 4 H 4。中子衍射数据表明，氢化物离子占据了主晶格中的赤道阴离子位点，因此，Ru和Ni阳离子位于仅包含氢化物配体的平面中，这种独特的结构特征与存在于其中的CuO 2片明显平行。超导铜酸盐。DFT计算证实了S =Ni +和S = 0，Ru 2+的存在中心，但中子衍射和μSR数据未显示低至1.8 K的Ni中心之间的远距离磁序的证据。观察到的弱阳离子间磁耦合可归因于Ni- 3d和H 1s在超级原子中的重迭交流途径。
