Great attention has been paid to organic–inorganic hybrids in searching for single-phase multiferroics because of their flexible structure design. Here, a new [CuCl₄]²⁻ based organic–inorganic hybrid, (bix)CuCl₄·H₂O (bix = 1,4-bis(imidazol-1-ylmethyl)benzene), is synthesized via a simple solution method. Different from most [CuCl₄]²⁻ based organic–inorganic hybrids, tetrahedral [CuCl₄]²⁻ units in (bix)CuCl₄·H₂O are connected to each other through water molecules and form one dimensional chains. The coexistence of ferroelectric and antiferromagnetic ordering in (bix)CuCl₄·H₂O is demonstrated. Its spontaneous polarization and coercive field at room temperature are 2.03 μC cm⁻² and 0.32 kV cm⁻¹, respectively. Furthermore, (bix)CuCl₄·H₂O films with high quality can be easily prepared, which makes them suitable for application in device fabrication.

有机-无机杂化（1,4-双（咪唑-1-基甲基）苯）CuCl4·H2O中的铁电和反铁磁性

由于有机-无机杂化体的灵活结构设计，在寻找单相多铁性化合物方面已引起了极大的关注。在这里，通过一种简单的溶液方法合成了一种新的基于[CuCl ₄ ] ²⁻的有机-无机杂化体（bix）CuCl ₄ ·H ₂ O（bix = 1,4-双（咪唑-1-基甲基）苯）。。与大多数基于[CuCl ₄ ] ²⁻的有机-无机杂化材料不同，（bix）CuCl ₄ ·H _2中的四面体[CuCl ₄ ] ²⁻单元O通过水分子彼此连接并形成一维链。证明了（bix）CuCl ₄ ·H ₂ O中铁电有序和反铁磁有序并存。室温下其自发极化和矫顽场分别为2.03μCcm ^-2和0.32 kV cm ^-1。此外，可以容易地制备高质量的（bix）CuCl ₄ ·H ₂ O膜，这使其适合用于器件制造。
