Does Harvard have any inorganic/materials chemists besides Dan Nocera? I might be ignorant here, but I haven't seen Harvard being touted for its inorganic & materials division. Much less when compared to MIT for sure.
Also, I have heard some really, grossly, nasty stories of departmental infighting at Harvard. Word from several grad students there is that all Harvard PI's essentially hate each other and compete for lab space and resources, and the stress ultimately trickles down to their grad students. Granted, these stories were told primarily by the organic chemists in the top labs, so take it with a grain of salt, but this is something that I would ask about during visits.
I'm not sure what you are asking here. What do you mean by the "academic atmosphere?" Whatever it is, how is it relevant to your willingness(??) to go into academia? Based on your wording, it sounds like an academic position is not exactly what you want but something that you would be okay with.
