Abstract
An alternative to classical? In square-planar d8 complexes the metal ion can interact with axial H2O molecules either as a Lewis acid or as a Lewis base. Ab initio calculations predicted that uncharged PtII complexes form a hydrogen-bond-like interaction with H2O, in which PtII acts as a Lewis base. Such a nonclassical O-H Pt hydrogen bond has now been identified in crystals of trans-[PtCl2 (NH3)(N-glycine)] H2O by neutron diffraction.
