Using the crystallographic parameters of isostructural compounds, the unit cell parameters of RbCe2(PO4)3 and Rb2Ce(PO4)2·хH2O were calculated from X-ray powder diffraction data. The following values were obtained: for RbCe2(PO4)3, a = 17.494(1) Å, b = 6.7759(5) Å, c = 7.9831(5) Å, β = 102.875(4)°, V = 922.51(10), Å3, Z = 4 (space group C2/c); for Rb2Ce(PO4)2·хH2O, a = b = 6.8663(1) Å, c = 17.6562(5) Å, V = 832.42(3) Å3, Z = 4 (space group I41/amd). Thermal behavior analysis of the synthesized compounds was performed, including phase composition determination of the thermolysis products. The results demonstrate that the initial structures exhibit relative thermal stability, with decomposition onset temperatures of approximately 500°C. At higher temperatures, progressive thermolysis leads to the formation of CePO4 alongside RbPO3 or Rb4P2O7, depending on conditions.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"70 7","pages":"943 - 951"},"PeriodicalIF":1.5,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144897118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X-ray powder diffraction was used to confirm the target crystal structure and the absence of copper oxide impurities, as well as to show the nonlinear dependence of the average size of the coherent scattering region on the temperature and duration of the synthesis process. The scanning electron microscopy results showed that, in general, increasing the temperature and duration of the synthesis process leads to an increase in the length of the formed copper nanowires from 45 to 150 μm, i.e. under certain conditions, ultra-long structures are obtained. As a result, the aspect ratio varies from 782 to 2358 by altering the synthesis conditions.

Therefore, these compounds may be promising for the selection of optimal structures to be studied as active components of sensor devices. In order to achieve high sensing characteristics, the effect of the composition of the coordination sphere of O=Mo(X)P on these characteristics was analyzed by varying the axial ligand X and the substituent in the equatorial macrocyclic ligand. For this purpose, a complete kinetic description of the reaction with pyridine (Py, a classical example of highly volatile organic compound (VOCs)), proceeding as two consecutive two-way reactions, was developed in relation to (ethoxy)(oxo)[5,10,15,20-tetraphenylporphinato]molybdenum(V) (O=Mo(OEt)TPP) in toluene. The intermediates and final products were identified by UV-Vis, 1H NMR, and IR spectroscopy and mass spectrometry, and sensing activity parameters (time, numerical spectral response to the presence of Py, and the lower limit of Py determination) were studied.
