摘　　要：在水溶液中反应制得无色透明的标题化合物单晶 ,单晶X -射线结构分析表明 ,属单斜晶系 ,空间群P2 1,晶胞参数 :a=1.15 47(2 )nm ,b =1.430 9(3)nm ,c =1.5 495 (3)nm ,β =10 5 .41(3)° ,V =2 .46 81(9)nm3,Z =2 ,Dc=4.6 39Mg/m3,对 5 45 4个独立衍射点 (I>2δ(I) )进行全矩阵最小二乘法修正后 ,可靠性因子R =0 .0The single crystal of the title compound was prepared in aqueous solution, X_ray analysis shows that it belongs to monoclinic system, space group P2 1, unit cell: a=1.1547(2)nm, b=1.4309(3)nm, c=1.5495(3)nm, β=105.41(3)°,V=2.4681(9)nm 3, Z=2, Dc=4.639 Mg/m 3. The final residue factor, R=0.0487, was got from final refinement of 5454 observed reflections by means of full_matrix least_squares.
