报道了一种新型钴基钒酸氢盐化合物Co_（13.5）（OH）_6（H_（0.5）VO_（3.5））_2（VO_4）_6的磁性。这种新的磁性材料是使用常规的水热方法以单晶形式合成的。其晶体结构由单晶X射线衍射数据确定，并通过扫描电子显微镜进行了表征。它的晶体框架有一个dumortierite结构组成的大型六方和三角通道;大型六方通道包含一维链面共享CoO 6八面体连接到框架的VO 4四面体环，而三角通道被无序V2 O 4金字塔群链占据。这种材料的磁性进行了研究，通过直流磁测量，这表明反铁磁相互作用的发生。
The magnetic properties of a novel cobalt-based hydrogen vanadate, Co13.5(OH)6(H0.5VO3.5)2(VO4)6, are reported. This new magnetic material was synthesized in single-crystal form using a conventional hydrothermal method. Its crystal structure was determined from single-crystal X-ray diffraction data and was also characterized by scanning electron microscopy. Its crystal framework has a dumortierite-like structure consisting of large hexagonal and trigonal channels; the large hexagonal channels contain one-dimensional chains of face-sharing CoO6 octahedra linked to the framework by rings of VO4 tetrahedra, while the trigonal channels are occupied by chains of disordered V2O4 pyramidal groups. The magnetic properties of this material were investigated by DC magnetic measurements, which indicate the occurrence of antiferromagnetic interactions.
