Two isostructural tellurite phosphates Ni2MIITeIV2O2(PO4)2(OH)4(MII= Ni, Zn) havebeen synthe-sized via hydrothermal method. Both of them crystalize in monoclinic space group C2/m(No. 12). For Ni2ZnTeIV2O2(PO4)2(OH)4,a= 19.3247(10),b= 5.9697(3), c= 4.7737(2)Å, β= 103.637(5)°, V= 535.18(5)Å3, Z= 2, Mr= 727.94, S= 1.103, Dc= 4.517 g-cm-3, μ(MoKα) = 11.434 mm-1and F(000) = 672, the final R= 0.0369and wR= 0.1086for 639 observed reflections with I> 2σ(I). The crystal structure of Ni2MIITeIV2O2(PO4)2(OH)4(MII= Ni, Zn) features a 3Dframework composed of [Ni2O2(PO4)2]6-layers interconnected by [MTe2O2(OH)4]2+single chains. Different magnetic susceptibility results at low temperature of the two title compounds confirm that Zn(1) completely occupies the Ni(2) position but not partially substitutesboth Ni(1) and Ni(2) positionatoms. Additionally, the acentric TeO3(OH)2tetragonal pyramids are aligned in an antiparallel manner,resultinginthe crystallization of centrosymmetric (C2/m) crystal structureinstead ofthenon-centrosymmetric crystal structure. The investigation of the origin of centrosymmetric crystal structurewith strong dipole moment units provides deeper understandingfor future rational design for non-centrosymmetric crystal structure. © 2021 Fujian Institute of Research of the Structure of Matter.

Crystals of sodium tridecafluorodizirconate Na5Zr2F13 were synthesized under mild hydrothermal conditions, and the structure was refined by single-crystal X-ray diffraction. The compound crystallizes in monoclinic with crystallographic data： Mr = 544.39, C2/m （No. 12）, a = 11.5600（9）, b = 5.4759（4）, c = 8.3989（6） A°, β = 97.361（10）°, V= 527.28（7） A°^3, Z= 2, Dc = 3.429 g/cm^3, 2 = 0.71073A° ,μ = 23.48 cm^-1, F（000） = 504, T= 295 K, Ri = 0.0173 and wR2 = 0.0449 for 55 variables and 682 contributing uniqUe reflections. The crystal structure is constituted with sixand eight-fold sodium atoms, forming irregular trigonal prisms and irregular cubes, respectively. Here, the zirconium atoms are connected with seven fluorine atoms to form a mono-capped trigonal prism. [Zr2F13]^5- complex ions formed by comer-shared [ZrF7]^3- are comer- and edgeshared to [Na4F22] and [Na3F8] cages, leading to the network structure. Thermal analysis, X-ray excited luminescence and photoluminescence under UV light measurements were conducted on Na5Zr2F13 crystals.

A vanadyl phosphate containing a new member of tancoite-like single chain, （DAPH2）[VIVO（HPO4）2]·xH20 （x ≈ 0.2, DAP = 1,3-diaminopropane, C3H10N2）, has been synthesized under hydro（solvo）thermal conditions. It crystallizes in orthorhombic space group P21212 （No. 18） with a = 7.1730（14）, b = 19.252（4）, c = 8.6557（17） A, Z= 4, V= 1195.3（4）A3, C3H14.38N2P2VO9.19, Mr = 338.47, Dc = 1.881 g/cm3,μ（MoKa） = 1.138 mm-1 and F（000） = 692. The final full-matrix least-squares refinement converged to R = 0.0408, wR = 0.1046 for 2498 observed reflections with I 〉 2σ（I） and R = 0.0456 and wR = 0.1080 for all data （2750） and S = 1.001. Its one-dimensional 1 structure consists of tancoite-like ∞1 {vIVO（HPO4）2}2- single chains surrounded by DAPH22＋ ions and water molecules. The single chain is built from trans-corner-sharing octahedral {VIV= O…VIV} backbone loop-branched by HPO4 groups like staple forming a new member of tancoite single chain. Due to the special coordination of VIVO6, the ∞1 {VO（HPO4）2-} chain adopts a larger M-O-M angle （V-O-V = 135°） than those of tancoite chains reported before. The corner-sharing linear {VIV = O…VIV} chain structure also leads to a one-dimensional weak antiferromagnetic interaction at low temperature. The magnetic measurements confirm the 4＋ valence state of vanadium. IR and TG results of the title compound are also discussed.

金属有机框架(MOF)由于其结构新颖且功能丰富,是极具应用前景的一类新材料。粉末X射线衍射(PXRD)是一种传统的材料表征手段,被广泛应用于大学教学与科研中。通过分析不同方法制备的MOF-5的PXRD衍射峰实验强度与计算强度不相符的现象,激发学生对PXRD衍射峰强度公式赫尔/德拜-谢乐方程(Hull/Debye-Scherrer Equation)以及其中洛伦兹因子(Lorentz Factor)的兴趣。同时,尝试从构成洛伦兹因子的3个几何因子和晶体生长的择优取向深入探讨这种不一致产生的原因。此外,构筑了以PXRD原理、计算结果、实验结果以及晶体成核-生长理论之四位一体的新型大学化学综合实验。

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.
