A new potassium-nickel iron phosphate, KNiFe(PO), has been synthesized by solid-state reaction and structurally characterized by single-crystal X-ray diffraction and qualitative energy dispersive X-ray spectroscopy (EDS) analysis. The structure is built up by [FeO], [PO], and [NiO] coordination polyhedra, which are linked to each other by edge and corner sharing to form zigzag layers parallel to the plane. These layers are inter-connected by [PO] tetra-hedra and [NiO] octa-hedra common corners, leading to a three-dimensional framework delimiting large channels running along the [100] direction in which the K cations are localized.
一种新型磷酸钾镍铁（KNiFe(PO)）已通过固态反应合成，并通过单晶X射线衍射和定性能量色散X射线光谱（EDS）分析进行了结构表征。该结构由[FeO]、[PO]和[NiO]配位多面体构建而成，它们通过边共享和角共享相互连接，形成平行于 平面的锯齿状层。这些层通过[PO]四面体和[NiO]八面体的公共角相互连接，形成一个三维框架，界定了沿[100]方向延伸的大通道，K阳离子位于这些通道中。
