Hi, I'm just trying to read my notes and one part didn't make sense. In proton NMR, if a chemical shift of H is very downfield, does it indicate a square pyramid structure with an apical hydrogen? Because I thought hydrides in metal-hydrides are usually found upfield...For example in a structure such as: Ru(PPh3)3(OPh)(H) which is drawn as a square pyramid with an apical hydrogen my notes say that the chemical shift for the H is -22.7...did I make a typo??
Thanks.
