Kossiakoff (1985) pointed out that the most useful attribute of neutron diffraction studies of proteins (compared with X-ray diffraction) is their ability to locate hydrogen (or deuterium) experimentally. Recent advances in apparatus and data acquisition mean that this method will become increasingly valuable in the study of a-lactalbumin and lysozyme, especially in the location of water molecules and the dynamics of these proteins. An example of a recent application is that by Lehmann et al. (1985). 

The crystal engineering community is also at the forefront of work into new kinds of intermolecular interactions. Recent single-crystal neutron diffraction studies revealed detailed information on OH-. -tc interactions " and on unconventional hydrogen bonds to metal center- as] well as MH-. HX-type interactions, where MH is a hydridic metal hydrogen moiety, and HX contains protic hydrogen. 

Recently, Bau et al have determined the neutron diffraction single crystal structure of [N(CH3)4]3[(//5-H)2Rhi3(CO)24] and found that five-coordinate hydrogen atoms are located in the square pyramidal cavities on the surface of the Rhis cluster in positions that are almost coplanar with the Rh4 faces of the cluster. Again, through a comparison with neutron diffraction studies of related rhodium complexes, Bau et al. have shown a correlation between the Rh—H...
