High-pressure synthesis and crystal structure of the samarium meta-oxoborate γ-Sm(BO2)3

-Sm(BO was obtained via a high-pressure/high-temperature approach in a multi-anvil apparatus at 10 GPa and 1673 K. It crystallizes in the orthorhombic space group (no. 29) with the lattice parameters  = 18.3088(8),  = 4.4181(2), and  = 4.2551(2) Å. The compound was analysed by means of X-ray diffrac...

Summary:-Sm(BO was obtained via a high-pressure/high-temperature approach in a multi-anvil apparatus at 10 GPa and 1673 K. It crystallizes in the orthorhombic space group (no. 29) with the lattice parameters  = 18.3088(8),  = 4.4181(2), and  = 4.2551(2) Å. The compound was analysed by means of X-ray diffraction and vibrational spectroscopy. The structure is isotypic to that of the already known -oxoborates (BO (  = La−Nd) and built up of a highly condensed borate framework containing three-, four-, six-, and ten-membered rings. Next to neodymium, samarium represents the second rare earth element that forms the -, -, and -modification of the four known rare earth -oxoborate structure types.
