| Abstract: | The new vanadate BiMgVO5 has been prepared and its structure has been determined by single crystal X-ray diffraction: space group P21/n,  ,  ,  , β=107.38(5)°, wR2=0.0447, R=0.0255. The structure consists of Mg2O10] and Bi2O10] dimers sharing their corners with VO4] tetrahedra. The ranges of bond lengths are 2.129-2.814 Å for Bi-O; 2.035-2.167 Å for Mg-O and 1.684-1.745 Å for V-O. V-O bond lengths determined from Raman band wavenumbers are between 1.679 and 1.747 Å. An emission band overlapping the entire visible region with a maximum around 650 nm is observed. |
