Abstract

A new noncentrosymmetric aluminoborate (H2TETA)[Al(B 5O10)] (1), has been solvothermally synthesized by using triethylenetetramine (TETA) as the structure-directing agent. Single-crystal X-ray diffraction analysis reveals that the compound crystallizes in the orthorhombic space group Pna21 with unit cell parameters a = 12.9696(9) Å, b = 17.0035(8) Å, c = 7.3660(5) Å, V = 1624.41(18) Å3 and Z = 4. Its structure consists of AlO 4 tetrahedra and B5O10 clusters and possesses 8-, 11- and 14-ring channels with sra topology. Second-harmonic generation (SHG) measurements on the powder samples reveal that 1 exhibits moderate SHG signals approximately 1.5 times that of KH2PO4 (KDP).
