Abstract

The structure consists of infinite zigzag polyphosphate chains, running along the c-axis direction, linked by Ni²⁺ ions and delimiting large tunnels in which the K⁺ ions are located. Ni²⁺ ions form slightly distorted NiO₆ octahedra and the coordination numbers of the independent potassium cations are 8 and 10.

Single crystals of K₂Ni(PO₃)₄ were obtained by solid-state reaction. The structure consists of infinite zigzag polyphosphate chains, running along the c-axis direction, linked by Ni²⁺ ions and delimiting large tunnels in which the K⁺ ions are located. Ni²⁺ ions form slightly distorted NiO₆ octahedra and the coordination numbers of the independent potassium cations are 8 and 10.

期刊介绍： Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
