(*Studying Coordination Chemistry, "Crystal Field Theory" at school*)

Apparently, different sources spell this differently.

[Wikipedia][2], calls it the "Barycenter" (as does my school textbook)

Another book I have at hand (*Concise Inorganic Chemistry* Lee, J.D), prominently uses the term "Bari centre".

-----------

The center/centre distinction aside, what I've been able to glean from my books (and the internet), is that this term is spelled in *four* different ways (Wah! Such gross inconsistency in literature!):

 - Barycenter
 - Bary center
 - Baricenter
 - Bari center

But which one's correct (or at least, a more preferred term in Chemistry-literature)?
