Abstract
Mg3 –nNinBPO7 samples (n = 0–3) were synthesized by gel combustion followed by annealing at 980°C, cooled under inertial-thermal conditions, and then studied by X-ray powder diffraction analysis, IR spectroscopy, and X-ray fluorescence spectrometry. A crystalline phase of Ni3BPO7 with the β-Zn3BPO7 structure was experimentally obtained for the first time. When varying the composition of the samples from Mg3BPO7 to Ni3BPO7, in borophosphate, a region of coexistence of α‑Mg3BPO7 and β-Ni3BPO7 was discovered. Analysis of diffuse reflectance spectra of Mg1.5Ni1.5BPO7 showed the presence of Ni2+ cations in an environment different from the symmetrical octahedral or tetrahedral environment.
期刊介绍：
Doklady Chemistry is a journal that publishes new research in chemistry and chemical engineering of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
