Hexakis(3-bromo-2(1H)-pyridone)copper(II) perchlorate was prepared. Crystals and powdered bulk samples were characterized using IR, single-crystal and powder X-ray diffraction, combustion analysis, EPR and temperature-dependent magnetic susceptibility data. The complex crystallizes in the triclinic space group P$$\bar{1}$$1¯ and comprises a Jahn–Teller distorted Cu(II)–O6 coordination sphere with the ligands coordinated via the pyridone O-atoms. EPR and variable temperature susceptibility measurements show that the complex is well isolated magnetically in the lattice.

偶然合成的铜 (II) 配合物的结构和磁性能：[Cu(3-Br-2-pyone)6](ClO4)2

制备了高氯酸六(3-溴-2(1H)-吡啶酮)铜(II)。使用 IR、单晶和粉末 X 射线衍射、燃烧分析、EPR 和随温度变化的磁化率数据对晶体和粉末状大块样品进行表征。该配合物在三斜空间群 P$$\bar{1}$$1¯ 中结晶，并包含一个 Jahn-Teller 扭曲的 Cu(II)-O6 配位球，配体通过吡啶酮 O 原子进行配位。EPR 和可变温度磁化率测量表明，复合物在晶格中被很好地磁隔离。
