Molecular helicity in inorganic complexes; the preparation, crystal and molecular structure of bis(2,2′:6′,2″:6″,2‴:6‴,2″″-quinquepyridine)acetatodicopper(II) hexafluorophosphate monohydrate

Abstract

2,2′:6′,2″:6″,2‴:6‴,2″″-Quinquepyridine (L, quinquepy) forms 2:2 complexes with transition metal ions in which the ligands are twisted about the metals in a double helical arrangement reminiscent of nucleic acids.
