Single-crystal X-ray analysis revealed that the complex belongs to trigonal system, space group R-3c, with a = b = 10.999（2） A, c = 40.439（13） A, V = 4237（2）A3, Z = 6, Dc = 1.410 g/cm3, Mr = 599.41, μ = 0.785 mm-1, F（000） = 1893, the final R = 0.0330 and wR = 0.0926（I 〉 2σ（I））. IR spectrum and compositional analyses（elemental analyzer and ICP） were used to characterize the composition of the product. TGA（Thermal Gravimetric Analysis） showed that complex Ⅰ remained stable until it is heated up to 200 ℃, indicating its good thermostability. The main transmission peak of complex Ⅰ in UV-Vis spectrum appeared at 290 nm, making it an eligible material for ultraviolet light filters（ULF）.展开更多

NSH-HMTA belongs to the triclinic system, space group Pi with a = 9.2534（6）, b = 13.3131（2）, c = 16.0373（2） A, α = 65.981（6）, β = 89.792（3）, γ = 89.677（4）°, Mr= 880.2, Z = 2, V= 1804.6（3） A3, μ = 1.254 mm-1, F（000） = 932, R = 0.0555 （1 〉 2σ（I）） and wR = 0.1908 for 19343 observed reflections. HMTA substitutes for water molecules are located at the para-positions, forming a stretching octahedral nickel ion unit. Thermo-gravimetric analysis shows that the dehydration temperature of NSH-HMTA is about 92℃. The characteristic UV peaks are approximately 10 nm red-shifted by the absorption of octahedral HMTA complex ion units.展开更多
