Data collections were performed at 20 °C on a Rigaku RAXIS RAPID IP diffractometer, using graphite-monochromated Mo Ka radiation (l = 0.71073 Å. The determination of crystal class and unit cell parameters was carried out by the Rapid-AUTO (Rigaku 2000) program package. The raw frame data were processed using Crystal Structure (Rigaku/MSC 2000) to yield the reflection data file. The structure was solved by use of SHELXTL program. Refinement was performed on F2 anisotropically for all the non-hydrogen atoms by the full-matrix least-squares method. The hydrogen atoms were placed at the calculated positions and were included in the structure calculation without further refinement of the parameters.

数据收集是用理学RAXIS RAPID IP单晶衍射仪在20摄氏度下进行的,采用经过石墨单晶单色的Mo Kalpha射线(波长=0.71073埃)。晶系和晶胞参数的确定是通过Rapid-AUTO程序包完成的。通过Crystal Structure程序将原始的衍射画面转换为衍射文件。使用SHELXTL程序解析结构。所有非氢原子的各项异性参数的精修采用以F(2)的基础上的全矩阵最小二乘法。所有氢原子都被固定在计算的位置上并参与结构因子的计算,但不对其参数进行精修。
