An alternative to classical? In square‐planar d 8 complexes the metal ion can interact with axial H 2 O molecules either as a Lewis acid or as a Lewis base. Ab initio calculations predicted that uncharged Pt II complexes form a hydrogen‐bond‐like interaction with H 2 O, in which Pt II acts as a Lewis base. Such a nonclassical OH⋅⋅⋅Pt hydrogen bond has now been identified in crystals of trans ‐[PtCl 2 (NH 3 )( N ‐glycine)]⋅H 2 O by neutron diffraction.
