[Cu2I2(tptz)]n的合成和晶体结构研究

Synthesis and Crystal Structure of [Cu_2I_2(tptz)]_n

用溶液法以碘化亚铜和tptz反应得到Cu(Ⅰ)的配位聚合物[Cu2I2(tptz)]n(1)(tpzt=2,4,6-tris(pyrazole-1-yl)-1,3,5-s-triazine),对该化合物进行了元素分析,红外光谱,XRD,热重等表征,并测定了它的单晶结构。配位聚合物[Cu2I2(tptz)]n(1)属单斜晶系,C2/c空间群,晶体学数据为:a=1.30683(17)nm,b=1.25425(16)nm,c=1.14732(15)nm,β=94.940(2)°,Z=4。tptz以双联吡啶形的配位方式和Cu(Ⅰ)配位形成一条Z字形的1D链。

The reaction of 2,4,6-tris（pyrazole-1-yl）-1,3,5-s-triazine（tptz） with copper（Ⅰ） halide in DMF gave a polymeric Cu（Ⅰ） complex [Cu2I2（tptz）]n（1）.The complex has been characterized by elemental analysis,IR,XRD,TG and its structure is established by X-ray diffraction single crystal structure analysis.Complex 1 crystallizes in the monoclinic space group C2/c,with a=1.306 83（17） nm,b=1.254 25（16） nm,c=1.147 32（15） nm,β=94.940（2）° and Z=4.Complex 1 is a zigzag chain with tptz in a bis-bipyridine-like coordination mode.
