ABSTRACT
Two barium-containing borates BaMBO4 (M = Al, Ga) were synthesized via the solid-state method under atmospheric pressure. The 3D configurations of BaGaBO4 and BaAlBO4 are comprised of ∞2[Ba4O16]24-/∞2[Ga4O10]8-/[B2O5]4- and ∞3[Ba4O16]24-/∞2[Al4O10]8-/[B4O10]8-, respectively, of which the [B4O10]8- units possess unusual edge-sharing [BO4]5- tetrahedra. From BaGaBO4 to BaAlBO4, the B-O units are transformed from corner-sharing to edge-sharing linkages, which arises from the directional shrinkage caused by the Ba-O and M-O skeletons. The phonon spectra of these two compounds do not show imaginary frequency at any wave vectors, indicating that both of them are kinetically stable.
