Title: Organometallic Chemistry
Post by: eddieq on January 04, 2005, 08:39:22 AM
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.
Eddieq

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

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

Is it
di-u-chlorodichlorobis(triphenylphosphine)palladium(II)?

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-?
