| 摘 要： | 1 INTRODUCTION Most materials with nonlinear optical pro- perties and electro-optical applications are either borates or phosphates. LBO(LiB3O5), KTP(KtiO- PO4), BBO(b-BaB2O4) and KDP(KH2PO4) are well- known commercially and extensively used for different optical elements. In recent years, the compounds combined both borate and phosphate groups have been synthesized and structurally characterized with quite different anionic partial structures. In particular, the use of hydrot… |

| Abstract: | A brilliant purple octahedral single crystal is hydrothermally synthesized by the reaction of CoCl2·6H2O, H3BO3 and H3PO4 in NaOH aqueous solution of CH3(CH2)15N(CH3)3Br, and its crystal structure has been characterized by single-crystal X-ray diffraction. The compound, NaCo(H2O)2BP2O8·H2O (Mr = 336.72), belongs to hexagonal, space group P6122 with a = 9.447(5), c = 15.83(1) (A。), V = 1223(1) (A。)3, Dc = 2.742 g/cm3, Z = 6, F(000) = 1002 and β= 2.606 mm－1. The three-dimensional framework in the compound is built up from the linkage tetrahedral ribbons, in which the BO4 and PO4 tetrahedra alternate with CoO6 octahedra. The sodium ions and water molecules are located within the free thread of the helical ribbons. |
