Abstract
A 2D open-framework zinc phosphate [C3N2H12][Zn2(HPO4)3] (1) was synthesized by solvothermal method. The inorganic anion layer is constructed from Zn2P2O12 cluster units and the interlayer spaces are filled by the diprotonated DAP molecules. The resultant compound had high purity and thermal stability by PXRD and TG analysis. This compound exhibited strongly temperature and humidity dependent proton conductivity, and its highest proton conductivity achieves 2.36 × 10−2 S.cm−1 at 100 %RH and 333 K. Moreover, the important effect of the dense hydrogen bond network in elevating the proton conductivity was explored through comparing the structure and proton conduction behavior between 1 and [C3N2H12][Zn(HPO4)2] (2), which synthesized via the same hydrothermal reaction process, and only a slight difference in the amount of DAP.
期刊介绍：
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
