Syntheses and Crystal Structures of Five Supramolecular Halides/Pseudohalides ([(ZnCl₄)(bppt)], [(CdCl₄)(bppt)], [(CdI₄)(bppt)], [(HgCl₃Br)(bppt)] and [(Ag₂Br₄)(bppt)]_n) Directed by 1,5-bis(pyridinium)pentane Cation

Abstract

Five supramolecular compounds oriented by bppt[1, 5-bis (pyridinium)pentane cation], [(ZnCl₄)(bppt)](1), [CdCl₄(bppt)](2), [(CdI₄)(bppt)](3), [(HgCl₃Br)(bppt)](4), and [(Ag₂Br₄)(bppt)]_n(5) were synthesized and characterized by X-ray crystallography. The crystal structures of 1–4 are mononuclear tetrahalidmetallates and show that they crystallize in monoclinic systems except compound 3, which is in triclinic system. Compound 5 is in monoclinic system, space group P2 (1)/n in which each monovalent Ag atom is tetrahedrally coordinated by four μ₂-Br atom ligands to constitute an infinite 1D (Ag₂Br₄ ²⁻) anion chain with the organic dication bppt²⁺ ([C₁₅H₂₀N₂]²⁺) trapped in it.
