Synthesis and Crystal Structure of a Three Dimensional Supramolecular Structure Constructed from Helicate Silver(I) Complex

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 1D channels containing the PF6- anions and H2O molecules. The crystal belongs to monoclinic, space group Cc with α = 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. 1731I2σ(I)].
