摘要： 从非水体系中制得了NH4ZnPO4单晶,并用x射线测定了晶体结构.晶体属六方晶系,P63空间群.晶胞参数:a=1.0688(2)nm,c=O.8706(2)nm,z=8,Dc=2.751g·cm-3.结构中的锌和磷均为四面体配位,且严格交替排列,无 Zn-O-Zn 和 P-O-P 联结方式.骨架中的氧均为桥氧.骨架结构中存在沿c轴方向伸展的规则的六元环直孔道.与其它磷酸盐不同的是,我们在该晶体骨架中首次观察到直线型的Zn-O-P联结方式.

Abstract: Single crystal of NH4ZnPO4 was synthesized from nonaqueous system and its crystal structure was determined using single crystal X-ray diffraction. The structure was solved by direct method and refined by full-matrix least-square method. The crystal is hexagonal with space group P63 and has a unit cell with a =1.0688(2) nm, c =0.8706(2) nm, V =0.8613(2) nm3, Mr=17838, μ =59.65 cm-1, Z =8, Dc=2.751 g·cm-3, R =0.035, Rw=0.078. There are no Zn_O_Zn and P_O_Plinkages in the structure. Both zinc and phosphorus atoms are four-coordinated to oxygen atoms. The framework structure contains six membered ring direct channels along c-axis. The linear Zn_O_Plinkage was first found in the structure of the phosphates.
