The very first normal-pressure tin borate SnBO, and the intermediate Sn[BO]F.

Aside from amorphous phases, only a single crystalline tin borate had been synthesised so far under high pressure. In this work, we present the very first crystalline ternary tin borate Sn3B4O9 synthesised under ambient pressure by decomposition of Sn3[B3O7]F above 500 °C. The crystal structure of Sn3B4O9 (P21/c, Z = 4, a = 768.

Synthesis and Characterization of the First Tin Fluoride Borate Sn [B O ]F with Second Harmonic Generation Response.

The new non-centrosymmetric tin fluoride borate Sn [B O ]F was synthesized hydrothermally, and was characterized by single-crystal and powder X-ray diffraction, vibrational spectroscopy, DFT calculations, second harmonic generation (SHG) measurements, thermogravimetry, and differential scanning calorimetry. Its SHG response is about 12 times that of quartz. The compound crystallizes in the non-centrosymmetric orthorhombic space group Pna2 with lattice parameters a=922.

The First Alkaline-Earth Fluorooxoborate Ba[B O F ]-Characterisation and Doping with Eu.

The very first alkaline-earth fluorooxoborate Ba[B O F ] was synthesised by solid state methods starting from Ba(BF ) , β-BaB O , and B O . The crystal structure derived from single-crystal X-ray diffraction (P2 /n, a=6.6384(2) Å, b=7.
