Isolation and X-ray crystal structure of [Cu(NH3)4H2O.18-crown-6]n2+[PF6]2n– a linear face-to-face hydrogen bonded chain copolymer
Abstract
X-Ray crystallography reveals that the [aquo-(tetra-ammine)copper]2+ ion forms a chain copolymer with 18-crown-6 in which each individual crown molecule is involved in no fewer than ten hydrogen bonds with four ammine ligands co-ordinated to the copper(II) centres in adjacent ions.
