Abstract
Solvothermal reactions of Zn(NO3)2·6H2O with isophthalic acid in the presence of potassium nitrate lead to an acentric three-dimensional (3D) hetero-metallic inorganic-organic hybrid framework [ZnK2 (m-BDC) 2 (H2O)2]n (1, m-H2BDC = benzene-1, 3-dicarboxylic acid). The crystal was characterized by elemental analysis, IR spectroscopy, TGA and single-crystal X-ray diffraction analysis. Complex 1 is of orthogonal crystal system, acentric space group Cmc21 with a = 19.764(6), b = 19.948(6), c = 12.039(4) Å, V = 4746(3) Å3, Z = 4, C32H20O19K4Zn2, Mr = 995.66, Dc = 1.393 g/cm3, F(000) = 2000 and μ = 1.426 mm-1. The final R = 0.0761 and wR = 0.1841. The crystal exhibits remarkable blue luminescence emissions with high quantum yield of 56.02% and displays modest powder SHG efficiency of about 0.7 times that produced by a potassium dihydrogen phosphate (KDP) powder. In addition, it also exhibits potential ferroelectric property.
