We have investigated structural, static magnetic and resonance properties of the new LiMgFe2(VO4)3 magnetic, which is produced from initial oxides Li2CO3, Fe2O3, MgO and V2O5 by solid-phase synthesis. Specific features of the trigonal crystalline LiMgFe2(VO4)3 structure with mixed Mg2+/Fe3+ cations in the same site with a symmetry described by a noncentrosymmetric space group P1 allow existence of competing magnetic exchange interactions with a high level of magnetic frustrations. We have found a dependence of static magnetic susceptibility on sample cooling conditions, which is typical for a spin-glass magnetic state. Keywords: new organic compounds, multi-component vanadates, crystalline structure, magnetic properties.
