我们提出了一种过渡金属氧化物氢化物，LaSrCoO3H0.7，它采用了前所未有的结构，其中氧化物链由氢化物阴离子桥接，形成一个二维的扩展网络的合成和结构表征。金属中心通过它们与氧化物和氢化物配体的键合而强烈耦合，以在高达至少350开尔文的温度下产生磁有序。合成路线是足够普遍的，允许一类新的含过渡金属的电子和磁性材料的预测。
We present the synthesis and structural characterization of a transition metal oxide hydride, LaSrCoO3H0.7, which adopts an unprecedented structure in which oxide chains are bridged by hydride anions to form a two-dimensional extended network. The metal centers are strongly coupled by their bonding with both oxide and hydride ligands to produce magnetic ordering at temperatures up to at least 350 kelvin. The synthetic route is sufficiently general to allow the prediction of a new class of transition metal-containing electronic and magnetic materials.
