Chair 3D Co(II) phosphite frameworks have been prepared by the ionothermal method. It belongs to chiral space group P321, and the whole framework can be topologically represented as a chiral 4-connected qtz net. It shows a multistep dielectric response arising from the reorientation of Me-DABCO in the chiral cavities. It can also serve as a pron conductor with high conductivity, 1.71 × 10 S cm, at room temperature, which is attributed to the formation of denser hydrogen-bonding networks providing efficient proton-transfer pathways.
通过离子热法制备了椅式三维钴（II）亚磷酸酯骨架。它属于手性空间群P321，整个骨架在拓扑结构上可表示为手性4-连接的石英网。它表现出由手性空腔中甲基二氮杂环庚烷的重新取向引起的多步介电响应。它还可以作为一种质子导体，在室温下具有1.71×10 S cm的高电导率，这归因于形成了更密集的氢键网络，提供了有效的质子转移途径。
