Neutron diffraction complexes, prior

Prior Neutron Diffraction Work on Transition Metal Hydride Complexes... 

This area developed from the x-ray and neutron diffraction work of Brammer, who first drew attention to the N-H...Pt interactions in a complicated square planar Pt(II) amine structure in 1991. In this work, also cited were prior structures proposed as examples of the same type of interaction. Starting from a square planar Pt(II) complex, an N-H bond is typically located in the otherwise vacant fifth coordination position of a square pyramid (4) with d(H... Pt) near 2.25-. The H... 0 distance in a classical hydrogen bond is often around 1.8 A, or 0.4 A longer than the van der Waals radii of O. If...
