Paramagnetism and Diamagnetism
Paramagnetism is a phenomenon where an atom or a molecule has unpaired electrons in its outermost shell, and thus, when it is exposed to a magnetic field, the unpaired electrons align themselves parallel to the magnetic field, causing the substance to be attracted to the magnetic field.
Diamagnetism, on the other hand, is a phenomenon where all the electrons in the outermost shell of an atom or a molecule are paired, and thus, when exposed to a magnetic field, the substance is repelled by the magnetic field.
Complex of Ni(II)
The complex of Ni(II), [NiCl2(PPh3)2], has a Ni(II) ion at its center, which has two unpaired electrons in its outermost shell, making it paramagnetic. The complex has a square planar geometry, and the two PPh3 ligands are cis to each other.
Isomers of Ni(II) complex
The complex has only one isomer, which is shown below:
[NiCl2(PPh3)2]
Complex of Palladium (II)
The analogous complex of Palladium (II), [PdCl2(PPh3)2], has a Pd(II) ion at its center. However, the Pd(II) ion has all its electrons in the outermost shell paired, making it diamagnetic. The complex has a square planar geometry, and the two PPh3 ligands are cis to each other.
Isomers of Pd(II) complex
The complex has two isomers, which are shown below:
[PdCl2(PPh3)2] (cis-isomer)
[PdCl2(PPh3)2] (trans-isomer)
Conclusion
In conclusion, the complex of Ni(II), [NiCl2(PPh3)2], is paramagnetic and has only one isomer, while the analogous complex of Palladium (II), [PdCl2(PPh3)2], is diamagnetic and has two isomers.
