!--[if gte mso 9]> In the course of an investigation to prepare the hypothetic new double perovskite La3Co2VO9 with Co2+ and V5+in octahedral sites, we obtained the new simple perovskite LaCo0.71(1)V0.29(1)O2.97(3) as the main phase. The pure compound was then synthesized by the citrate decomposition method. The crystal structure was studied by X-ray (PXRD) and powder neutron diffraction (PND). Physical properties were characterized by X-ray absorption spectroscopy (XAS), X-ray emission spectroscopy (XES) andthermogravimetric analysis (TGA). Rietveld refinements were performed in the orthorhombic space group Pnma (#62). Refined cell par
