| dc.description.abstractEn | The new compound K2CoV2O7 has been synthesized by a solid state reaction route. Its crystal structure has been determined using powder X-ray diffraction data (PXRD). The compound K2CoV2O7 crystallizes with the melilite-type structure with the tetragonal unit cell parameters a = 8.4574(1), c = 5.5729(1) Å and the space group View the MathML sourceP4−21m. The structure consists of [CoV2O7]2− layers perpendicular to the c axis separated by K+ layers. The [CoV2O7]2− layers consist of corner-sharing CoO4 tetrahedra and V2O7 pyrovanadate units, the linkage of these tetrahedra forming five-membered rings. The K+ cations occupy distorted square antiprisms of oxygen atoms. The magnetic susceptibility of K2CoV2O7 follows the Curie law χT = C with an effective magnetic moment μeff = 4.71 μB. | |
