合成了螺旋配合物C38H29AgF6N6O0.5P并进行了元素分析、红外光谱表征和单晶X射线衍射分析。配合物为单螺旋结构,Ag(I)原子呈现扭曲的四方锥配位构型。晶体中螺旋体芳环间存在的π…π和C-H…π作用使其形成具有一维通道的三维网状结构,通道内填充有PF6-离子和结晶水分子。该晶体属于单斜晶系Cc空间群,晶胞参数分别为:a=1.7823(7)nm,b=3.1382(14)nm,c=0.8407(4)nm,β=116.492(9)°,V=4.209(3)nm3,Z=4,Mr=830.51,dc=1.311 g.cm3,T=293(2)K,μ=0.577 mm-1,F(000)=1676,R1=0.0766,wR2=0.1731[I>2σ(I)].

A new helicate silver （ Ⅰ ） complex C38 H29 AgF6 N6 O0.5 P was synthesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The complex exhibits a singlestranded helix with the Ag （Ⅰ） atom having a distorted square pyramidal configuration. In the crystal structure C - H...π and π - π stacking interactions between the aromatic groups of the helices lead to a three-dimensional network with 1 D channels containing the PF6 - anions and H2O molecules. The crystal belongs to monoclinic, space group Cc with a = 1. 7823（7） nm, b = 3. 1382（14） nm, c = 0. 8407 （4） nm,β= 116.492（9）°, V= 4.209（3） nm3, Z = 4, Mr = 830.51, de= 1.311 g·cm3, T = 293（2） K,μ= 0.577 mm1, F（000） = 1676, R1 = 0.0766, ωR2 = 0. 1731[1〉2σ（1）].
