Abstract

Single crystals of two new metal tellurates BiMTeO6 (M = Al, Ga) with a honeycomb layered structure were obtained by the molten flux method and characterized. The BiMTeO6 compounds both crystallize into a non-centrosymmetric trigonal space group of P312 (no. 149) with cell parameters of a = 5.0667(8) Å, c = 4.9920(16) Å and a = 5.107(3) Å, c = 4.932(6) Å, respectively. The non-centrosymmetry of BiAlTeO6 and BiGaTeO6 originates from the packing order of the octahedra. In these two structures, TeO6 octahedra and MO6 octahedra share edges and form a honeycomb open-framework with [TeMO6] layers. The layers of [MTeO6] and [BiO6] alternate and are connected along the c-axis by corner-sharing oxygen atoms to form the three-dimensional framework. The chiral compound BiGaTeO6 exhibits a powder second harmonic generation (SHG) response of ∼0.2 times that of potassium dihydrogen phosphate (KDP) and an absorption edge of 355 nm.
