Syntheses, Crystal Structures, and Ultraviolet Properties of a Coordination Polymer [(Ag₂I₄)(EV)]_n

Abstract

In this article, we describe the synthesis of a novel onedimensional (1D) polymer {[(Ag 2 I 4 )(EV)]} 1 by the reaction of metal iodides with ethyl viologen dibromide (EV), and the results are characterized by x-ray crystallography and infrared (IR) spectroscopy. The compound 1 crystallizes in a tetragonal space group P4(2)/mnm with a = 12.5133(8) Å, b = 12.5133(8) Å, c = 7.1014(9) Å, α = 90 • , β = 90 • , γ = 90 • . In the anion, each monovalent Ag atom is tetrahedrally coordinated by four µ 2 -I atom ligands to constitute an infinite 1D (Ag 2 I 4 2− ) anion chain with the organic dication EV ([C 14 H 18 N 2 ] 2+ ) trapped in it.
