Syntheses and structural characterizations of novel molten alkali metal borates In this study, two novel alkali metal borates were synthesized by the borate fusion method, and an organic compound was synthesized by the solution method, in which the borate fusion method and the resulting borate compounds were emphasized. Compared to the hydrothermal method, borate fusion method is simpler and is able to introduce boron atoms more easily. All the structural data of the compounds were collected by a single crystal diffractometer and then analyzed. Both of the two borates were characterized by X-ray powder diffraction, IR and TGA. The three compounds synthesized in this paper include: (1) NaZnB3P2O10(OH)2•1.17H2O (2) RbB5O7(OH)2•H2O (3) C16H10O8•H2O Borophosphate NaZnB3P2O10 (OH) 2 • 1.17H2O belongs to hexagonal crystal system and P6(3)/m space group. Its unit cell parameters include a = 1.17272 (3) nm, c = 1.21317 (6) nm, γ = 120 °, V = 1.44491 nm3, Z = 6, R1 = 0.0679 and wR2 = 0.1566. The compound is a novel three-dimensional structure consisting of both 12-membered-ring and six-membered-ring pores. Pentaborate RbB5O7 (OH) 2 • H2O belongs to the monoclinic crystal system and P2/n space group. Its unit cell parameters include a=0.7640(2)nm, b=0.9019(3)nm, c=1.0833(3)nm, β=103.681(5)°, V=0.7252(4) nm3, Z=2, R1=0．0737 and wR2=0.1588. Boron-oxygen polyanion unit [B5O7(OH)2]- is connected with the adjacent unit [B5O7(OH)2]- by O atoms that form infinite chains, which are further connected by O atoms and Rb+ ions that form a three-dimensional chiral structure. C16H10O8•H2O belongs to the triclinic crystal system and P1 space group. Its cell parameters include a=0.71765(1)nm, b=0.94677 (2)nm, c=1.19301(2)nm, α=,106.013(1)°, β=100.098(1)°, γ=96.753(1)°, V=0.75518(2) nm3, Z=2.Dihedral angle between the two benzene rings is 71.63(2)°. Borate fusion method used herein is easily handling and is able to introduce boron atoms readily, which has been successfully applied in the syntheses of lithium battery cathode materials. Borates that are of macro-ring and chiral structures prepared in this paper will facilitate the innovation of borate materials and lay a solid foundation for the development of more novel materials with special functions. |
