Реферат:	eng: Detailed study of the BaB2O4-BaF2-BaO system resulted in the discovery of the new Ba7(BO3) 4-xF2+3x solid solution belonging to the BaF 2-Ba3(BO3)2 section. The distinguishing feature of the crystal structure of Ba7(BO 3)4-xF2+3x phase is its extensive (BO 3)3- ↔ 3F- anionic isomorphic substitution, confirmed by X-ray diffraction study of Ba7(BO 3)3.51F3.47 (x = 0.49) single crystals (space group P63; a = 11.18241(11) Å, c = 7.23720(8) Å). The area of homogeneity for Ba7(BO3)4-xF 2+3x solid solution spans between Ba7(BO3) 3.35F3.95 and Ba7(BO3) 3.79F2.63 compositions (0.21 < x < 0.65). Also, a new orthorhombic phase with a tentative composition of Ba5(BO 3)3F has been identified in XRD powder patterns and indexed with cell parameters a = 7.605 Å, b = 14.843 Å and c = 10.291 Å. © The Royal Society of Chemistry 2012.
