प्रश्न
Discuss the nature of bonding in the following coordination entity on the basis of valence bond theory:
[Co(C2O4)3]3−
Advertisements
उत्तर
Electronic configuration of Co (Z = 27) = [Ar] 3d74s2
Electronic configuration of Co3+ = [Ar] 3d64s0
\[\ce{C2O^{2-}_4}\] is a strong field ligand due to which electrons are paired.
Oxalate is a weak field ligand. Therefore, if cannot cause the pairing of the 3d orbital electrons. As there are 6 igands, hybridization has to be ether sp3d2 hybridization.
[Co(C2O4)3]3− involves d2sp3 hybridization, forms an octahedral, inner orbital complex as per valence bond theory.
Hence, it is clear that [Co(C2O4)3]3− is a diamagnetic and octahedral complex.
