Low spin configuration are rarely observed in tetrahedral coordination entity formation. Explain.

(a) Write the co-ordination number and oxidation state of platinum in the complex [Pt(en)_(2)Cl_(2)] (b) Low spin configuration are rarely observed in tetrahedral co-ordination entity formation . Explain .

Explain the terms Coordination entity

Assertion : In tetrahedral complexes low spin configuration are rarely observed . Reason : Delta_(t) = ((4)/(9)) Delta_(0)

Assertion : In tetrahedral complexes low spin configuration are rarely observed . Reason : Delta_(t) = ((4)/(9)) Delta_(0)

Why are low spin tetrahedral complexes not formed?

Statement-1: All tetrahedral complexes are mainly high spin and the low spin configurations are rarely observed. Statement-2: Delta_(t) is always much smaller even with stronger field ligands and it is never energetically favourable to pair up the electrons.
