If one metal is coordinated to one of the carboxylate oxygens(in ligand), what is its representation using [eta] and [mu]? If one metal is coordinated to both carboxylate oxygens, what is its representation using [eta] and [mu]? If possible please explain me how you decided them.
eta and mu are notations used to describe the bonding in coordination compounds. eta-is the dentisity of the ligand. That is if you consider carboxylate, to how many metals the functional group is bonded. It is usual to have eta- 1, 2 or 3 for carboxylate. However, mu is notation to express the bridging mode of coordination. If one off the O-atom of carboxylate is bonded to two metal atoms, then it is represented as mu-bridging.
I agree with Dr.Sunil about the representation of eta and mu notations. Moreover you can represent them in the for of mu1-OCO or mu2-OCO or some more motations. Please refer the following references:

Have a nice day ahead..!!!!!!!!!
