Organometallic Chemistry
« 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.

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

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

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
