Contrasting crystallographic signatures of Ag(i)- and Cu(ii)-N6,N6′- bisadenine complexes: extended vs. foldback geometries†
Abstract
We report crystallographic studies with N6,N6′-crosslinked bisadenine derivative, where complexation with Ag(I) exhibits a pentacoordination mode affording a molecular box, while interaction with Cu(II) results in an intramolecular complex.
