One-dimensional Hydrogen-bonded Chloride-Hydrate Assembly {[(H2O)4Cl2]2–}∞

Abstract

A hydrogen-bonded chloride-hydrate assembly {[(H2O)4Cl2]2−}∞ has been ion-countered by the complex cations [Fe([9]aneS3)2]2+ ([9]aneS3 = 1,4,7-trithiacyclononane). In {[(H2O)4Cl2]2−}∞, four water molecules and two chloride ions are self-assembled to form a one-dimensional supramolecular array of O-H···O and O-H···Cl hydrogen bonding, which consists of fused fourand six-membered rings. The discrete cation [Fe([9]aneS3)2]2+ has a nearly regular octahedral FeS6 core with an average Fe-S bond length of 2.2586(5) Å .
