Реферат:	eng: The LiBa12(BO3)(7)F-4 crystals doped Nd3+ and Pr3+ were grown from high-temperature solution melts, using the TSSG method. All the samples have the wide absorption band in the visible range of 350-650 nm related to the dichroism, which is typical for other colored "antizeolites". Strong radiation bands are associated with well known electronic transitions of Pr3+ (P-3(0) -> H-3(6) at 630 nm, P-3(0) -> F-2(2) at 670 nm) and Nd3+ (F-4(3/2) -> I-4(9/2) at 875 nm, F-4(3/2) -> I-4(11/2) at 1054 nm). In addition crystals of Nd-doped barium fluoride borate solid solutions NdxBa12(BO3)(8-x)F-6x were grown from high temperature solution. Using X-ray single-crystal diffraction, the structure was solved and refined in I4/mcm space group that are similar to other colored "antizeolites" built with the positively charged framework of [Ba-12(BO3)(6)](6+) cation pattern which contains channels built of alternating barium cubes and anticubes. According to the structure refinement of NdxBa12(BO3)(8-x)F-6x, cube channel segments are populated mainly by [F-4](4-) and [NdF4](-) clusters, whereas anticube ones - by (BO3)(3-) anions.
