[Mn(Cr2O4)2(H2O)2], I think this one may be dioalatodiaquomanganate (III) BUT I'm not too sure.
Thanks
Few points to remember :-
1.) First of all, in this complex there are aqua and chromate ligands. We write them in alphabetical order irrespective of the prefix di, tri etc. Therefore first we will write aqua and then chromate.
2.) Also 2 chromate ligands will be written as bischromato because dichromato will refer to Cr
2O
7 not (Cr
2O
4)
23.) The oxidation state of Mn here is IV not III because aqua is a neutral ligand and chromate has -2 charge.
4.) Since this complex is a neutral complex so instead of manganate we will write manganese
So I think its correct name will be diaquabischromatomanganese(IV)
could i please get some help naming these two compounds:
[PdI2(ONO)2(H2O)2]
Please first try it yourself
