用单温度梯度气相法生长了线度达1.1mm的C_(70)单晶.经外形和四圆X射线衍射分析,在室温下,C_(70).单晶为理想的hcp结构,晶格常数分别为a=b=1.0615nm,c=1.7246nm,c/a=1.625.
The single crystals of C 70 with a linearity of 1.1 mm were grown by single-temperature gradient gas-phase method.According to the shape and the four-circle X-ray diffraction analysis, C 70 single crystal was the ideal hcp structure at room temperature, The constants are a = b = 1.0615 nm, c = 1.7246 nm, c / a = 1.625, respectively.
