The synthesis, structural aspects, thermal and dielectric analysis for new members of the ferroic family, polynuclear Bi(III) and Sb(III) halide complexes based on a pyrazolium cation with the formulas (C₃N₂H₅)[BiCl₄]·H₂O and (C₃N₂H₅)[SbCl₄]·H₂O, are presented. The former compound was found to undergo a ferroic phase transition of the ferroelastic type at 213/219 K (cooling/heating scans), whereas, the latter one exhibited a piezoelectric feature in the dielectric response function. The molecular motions of pyrazolium cations were analyzed based on the spin–lattice relaxation time of ¹H NMR measurements.

具有一维阴离子结构的有机-无机杂化材料的铁弹性和压电性：相似但相异†

基于吡唑鎓阳离子并具有式（C ₃ N ₂ H ₅）[BiCl ₄ ]的铁族新成员，多核Bi（III）和Sb（III）卤化物配合物的合成，结构方面，热和介电分析·H ₂ O和（C ₃ N ₂ H ₅）[SbCl ₄ ]·H ₂O，呈现。发现前一种化合物在213/219 K时经历了铁弹性类型的铁相转变（冷却/加热扫描），而后一种则在介电响应函数中表现出压电特征。吡唑鎓阳离子的分子运动基于¹ H NMR测量的自旋-晶格弛豫时间进行了分析。
