摘　　要：采用流变相反应法合成了苯甲酸氢铜的大颗粒单晶,借助元素分析、四圆单晶衍射分析表征其组成和晶体结构,得到的晶体学数据如下:苯甲酸氢铜为单斜晶系,空间群P21/n,a=1.079 9(2)nm,b=1.178 0(2)nm,c=1.530 3(3)nm,β=91.35(3)°,V=1.946 1(7)nm3,Z=4,ρcalc=1.460,ρexp=1.455 g/cm3。μ=1.156 mm-1,F(000)=876,S=0.990,最终的偏离因子R=0.056 0和wR=0.075 0[I>2σ(I)]。用磁天平测定了晶体的磁化率。借助扫描电子显微镜研究了原料反应物颗粒的大小和生长单晶的颗粒大小存在有密切关系,探讨了在流变相体系中的化学反应机理和单晶生长机理,发现在流变相体系中存在有分子识别和自组装功能。Great grain single crystal of Cu（C6H5CO2）3H was synthesized by the rheological phase reaction method and the composition and crystal structure were characterized by elemental analysis,X-ray single crystal diffraction analysis.The crystallography data of Cu（C6H5CO2）3H are monoclinic,P21/n space group,a=1.079 9（2）nm,b=1.178 0（2）nm,c=1.530 3（3）nm,β=91.35（3）°,V=1.946 1（7）nm3,Z=4,ρcalc=1.460,ρexp=1.455 g/cm3.μ=1.156 mm-1,F（000）= 876,S=0.990,R=0.056 0 and wR=0.075 0[I2σ（I）].The magnetic susceptibility was measured by the magnetic balance.The close relationship between the size of the single crystal growth and the granularity of raw materials was studied by scan electron microscope and the possible mechanism of chemical reaction was also discussed.It is found that there is the self-assemble function and multi-position identification function in the rheological phase system.
