"The number is ZERO..........."The number is ZERO...........

Explanation:

Co^(3+)Co3+ has a d^6d6 electronic configuration.......and these are classically LOW SPIN, especially with strong field ligands such as cyanide.........

[Co(C-=N)_6]^(3-)[Co(CN)6]3 is thus diamagnetic with no unpaired electrons.
