| Реферат: | eng: Studied LixNa1-xBa12(BO3)(7)F-4 (P4(2)bc) solid solution belongs to the,new class of "antizeolite" borates with [Ba-12(BO3)(6)](6+) cation pattern, Which contains Channels filled by anionic dusters. Optical-quality crystals were grown from the compositions with different sodium-lithium ratio. The results of Rietveld refinement based on, powder data demonstrate linear increase of parameter a and unit cell volume with Na/(Na + Li) ratio in cation site. Parameter c is less sensitive to the changes in stoichiometry, which is consistent with channel topology of LixNa1-xBa12(BO3)(7)F-4 structure. Distinctive feature of LixNa1-xBa12(BO3)(7)F-4 crystals is their deep purple color, which is due to both hole-type and electron-type centers. Crystals are characterized by linear dichroism effect.
