9c.3d

Postby Victor James 4I » Thu Dec 05, 2019 11:50 pm

asks to write the formula for sodiumbisoxalato(diaqua)ferrate(III)

I got Na[Fe(OH2)2(C2O4)] but the answer is Na[Fe(OH2)2(C2O4)2].

in lavelle's slides it said "if ligand has name with di, tri, tetra, or polydentate then use prefixes bis-, tris-, tetrakis-, pentakis-"
so i assumed since the prefix is bis then theres one ligand that binds two sites, but I guess I just dont understand the statement from the slides

Oxalate is polydentate (Bidentate) so that is the reason it has the prefix "bis-" in front of it. The "bis" prefix suggests that there are 2 oxalate ligands that are attached to the transition metal, which explains why the answer is Na[Fe(OH2)2(C2O4)2].
