摘要

The magnetic properties of a novel cobalt‐based hydrogen vanadate, Co 13.5 (OH) 6 (H 0.5 VO 3.5 ) 2 (VO 4 ) 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 CoO 6 octahedra linked to the framework by rings of VO 4 tetrahedra, while the trigonal channels are occupied by chains of disordered V 2 O 4 pyramidal groups. The magnetic properties of this material were investigated by DC magnetic measurements, which indicate the occurrence of antiferromagnetic interactions.
