摘　　要：本文采用水热合成法制备了一个三维手性大孔开放骨架磷酸镓Ga16P16O75.4[1,6-C6H18N2].[C2H10N2].2H2O(简称Hit-5)。反应起始原料摩尔配比为:1 GaOOH:15 H3PO4:7.5 H2N(CH2)6NH2:0.5 C2H8N2:555H2O。Hit-5属正交晶系,P21212空间群,晶胞参数:a=0.8671(1)nm,b=1.7945(1)nm,c=0.9101(1)nm,β=108.33(1)°,V=1.3443(2)nm3,Z=4。Hit-5的骨架是由Ga3P3六聚体和Ga4P4八聚体两个不同的二级结构单元通过共顶点联接构成三维纳米孔结构,在[001]方向呈现16-元环孔道。A new chiral large microporous gallophosphate compound Ga16 P16 O75·4 [ 1,6-C6 H18 N2 ] [ C2H10 N2 ] 2H2O has been synthesized under the hydrothermal conditions. The molar ratio of the initial raw mixture was 1 GaOOH： 15 H3PO4- 7. 5 H2N （ CH2 ）6NH2： 0. 5 C2H8N2：555 H2O. It crystallizes in the monoclinic, space group P21212, with α = 0. 8671 （ 1 ）nm, b = 1. 7945 （ 1 ）nm, c = 0. 9101 （ 1 ）nm, β = 108.33 （ 1 ） °, V = 1. 3443 （ 2 ） nm^3 and Z = 4. The three-dimensional nanoporous network is built up from two different secondary building units （SBU-1 and SBU-2）. The 16-membered ring channels are shown along [001 ] direction.
