Hi,

I tried to use Gaussian03 to do geometrical optimization of a phosphate anion and then to calculate its charges. 
I used for the geometry calculation HF/6-31G(d) Opt NoSymm and HF/6-31G(d,p) Opt NoSymm and then for the charge HF/6-31G* pop=mk iop(6/33=2) and HF/6-31G** pop=mk iop(6/33=2) respectively.
I had an output for the geometry calculations, but not for the charges.
I would like to ask you what the multiplicity is for system given that electrons delocalised.
Also, what basis set shall I use?

Thank you,
