The number of unpaired electron in [Pt(CN)_4]^(2-) ion having square planar geometry (At.No. of Pt=78) is

The d-orbitals participating in hybridisation of metal atom may be from the n & (n-1) shell. This depends on the nature of metal and nature of ligand. The complexes involving the inner d-level (inner orbital complexes) results when the ligand is a powerful (or) strong ligand results in a diamagnetic (or) low spin complexes. A weak ligand usually results in the formation of outer orbital complex (or) high spin complex. Number of unpaired electrons present in [Fe(CN)_(6)]^(4-)&[Fe(H_(2)O)_(6)]^(2+) are respectively.
