N2 - In this work, we present a new borate, Ag3B6O10Br, as well as thermal properties of two recently reported members of M3B6O10X family, Ag3B6O10(NO3) and Na3B6O10I. The structure of Ag3B6O10Br is non-centrosymmetric, Pnm21, and exhibits a new version of packing the ionic Ag–Br and covalent B–O frameworks. The non-centrosymmetry is induced by alternation of disordered and ordered borate “layers” normal to a. The Ag–Br sublattice is also strongly disordered and exhibits pronounced ahnarmonicity of thermal vibrations modeled using the Gram – Charlier series. Thermal behavior of Ag3B6O10Br, Ag3B6O10(NO3) and Na3B6O10I was characterized using variable-temperature powder X-ray diffraction and thermal analysis. The thermal behavior of Ag3B6O10Br (αa = −0.5, αb = −7.4, αc = 41.5 at 200°С), Ag3B6O10(NO3) (αa = 4.5, αb = 4.8, αc = 31.8 at 200°С), and Na3B6O10I (αa = 9.4, αb = −1.2, αc = 48.3 at 200°С) is strongly anisotropic due to the alignment of the hexaborate B6O13 groups in the structure.
