(a) What type of isomerism is shown by the complex ?
(b) Why is paramagnetic while. is diamagnetic ?
(Atomic number of Ni = 28)
(c) Why are low spin tetrahedral complexes rarely observed ?
(a) show linkage isomerism
(b) is paramagnetic but is diamagnetic because is a strong ligand which cause pairing of electrons whereas CI is a weak ligand which cannot calls pairing
(c) In tetranedral , the d-element splitting is inverted and is smaller as compared to the octahedral field splitting. The orbital splitting energies are not sufficiently large for forcing pairing therefore, low spin configuration are rarely observed.
