Compounds {[Ag(1)](PF6) · 2(CH3NO2)}n 2 and {[Ag(1)](ClO4) · 2(CH3NO2)}n 3, which are the first coordination polymers of 1, readily crystallize from solutions of the silver salt and 1 in noncoordinating nitromethane solvent and were characterized by X-ray crystallography. In these structures the ligand is hypodentate, coordinating only through four nitrile N-donors to act as a 3-connecting center. The distorted tetrahedral silver also acts as a 3-connecting center. In the extended structure the anions lie in pockets above and below the [3]-radialene core of the ligands, forming moderate and weak hydrogen bonds with four different molecules of 1. The anions are in close proximity to the electron-deficient [3]-radialene core of 1, forming weak anion-π interactions.en© 2009 American Chemical Society2-D Coordination Polymers of Hexa(4-cyanophenyl)[3]-radialene and Silver(I): Anion•••π-Interactions and Radialene C−H•••Anion Hydrogen Bonds in the Solid-State Interactions of Hexaaryl[3]-radialenes with Anions2-D Coordination Polymers of Hexa(4-cyanophenyl)[3]-radialene and Silver(I): Anion (.)(.)(.) pi-Interactions and Radialene C-H(.)(.)(.)Anion Hydrogen Bonds in the Solid-State Interactions of Hexaaryl[3]-radialenes with AnionsJournal article002009076010.1021/cg90023020002667086000592-s2.0-6684913808238839Sumby, C.
