Single crystals of KNi(PO) were obtained by solid-state reaction. The structure consists of infinite zigzag polyphosphate chains, running along the -axis direction, linked by Ni ions and delimiting large tunnels in which the K ions are located. Ni ions form slightly distorted NiO octa-hedra and the coordination numbers of the independent potassium cations are 8 and 10.
通过固态反应获得了KNi(PO)的单晶。其结构由沿z轴方向延伸的无限之字形多磷酸盐链组成,这些链由镍离子连接,并界定了钾离子所在的大隧道。镍离子形成略微扭曲的NiO八面体,独立钾阳离子的配位数分别为8和10。
