Hello i am a newbie if u could help me i'd appreciate it.
I have a homework i cant solve ... i have searched for the IUPAC nomenclature of the following organometallic compounds
1. [Co(NH3)4(H2O)Br](NO3)2
2. Na[Au(CN)2 ]
3. [Ni(CO)2(Ph3P)2 ]
4.Na3[Fe(C2O4)3 ]
but i haven been able to get them. I have even used ChemFinderTM.
Please whatever u can do to help me , i will appreciate it.
God bless.

Note. There is an error - instead argenate should be argentate in Table 3

1. [Co(NH3)4(H2O)Br](NO3)2
aquabromotetraamminecobalt(III) nitrate
2. Na[Au(CN)2]
sodium dicyanoargentate(I)
3. [Ni(CO)2(Ph3P)2]
dicarbonylbis(triphenylphosphine)nickel(II)
4.Na3[Fe(C2O4)3]
sodium trioxalateferrate(III)
or
sodium tris(ethanedioate)ferrate(III)

sodium dicyanoaurate(I)
tetraammineaquabromocobalt(III) dinitrate
dicarbonylbis(triphenylphosphine)nickel(0)
sodium trioxalatoferrate(III)

Thanks for correcting my mistakes! ;)
aurate or argentate?
dinitrate, should we need to mention "di"? (NO3- is not a ligand)
-
2. Na[Au(CN)2 ]
Au - aurate
Ag - argentate
dinitrate - not abreviated form

hello,
thanx for the help i got my corrections.
How about naming this its also givin me head ache ... its just a practice question i saw in a book.
attached below:
-
I've actually made it. ;)
-
Is it
di-u-chlorodichlorobis(triphenylphosphine)palladium(II)?
-
2. Na[Au(CN)2 ]
Au - aurate
Ag - argentate
dinitrate - not abreviated form
e.g. calcium nitrate, we can omit "di-", right? How about [Co(NH3)4(H2O)Br](NO3)2?
-
di-u-chloro-af-dichlorobis(triphenylphosphine)palladium(II)? The rest is OK
Calcium nitrate is unambiguous because Ca shows oxidation state +2 only, but iron nitrate is ambiguous. Eearlier we used ferrous and ferric to distinguish between two oxidation states, now we use Fe(II) or Fe(III) or iron dinitrate (trinitrate). Using both indications, ie iron(III) trinitrate is not an error.
[Co(NH3)4(H2O)Br](NO3)2
tetraammineaquabromocobalt(III) nitrate or dinitrate

What's meant by -af-?
