How do you find paramagnetic and diamagnetic in coordination compounds?

Paramagnetic substances are attracted to magnetic fields. Many transition metal complexes have unpaired electrons and hence are paramagnetic. Molecules such as N2 and ions such as Na+ and [Fe(CN)6]4− that contain no unpaired electrons are diamagnetic.

Which of the following is tetrahedral and paramagnetic?

Complex K2[MnCl4] is tetrahedral and paramagnetic in nature because Mn is having +2 oxidation state and hence will have 3d54s0 configuration. Also Cl− is a weak field ligand and hence pairing of electrons won’t take place. Therefore The hybridization is sp3 and is paramagnetic in nature.

Is NiCl4 tetrahedral?

The complex [NiCl4]2- has tetrahedral geometry while [Ni(CN)4]2- has square planar geometry.

What is the hybridization of NiCl4?

Hybridization involved is dsp2 as participating orbitas are 3d, 4s and 4p.

Is NiCl4 2 high spin?

As there are unpaired electrons in the d-orbitals, NiCl42- is paramagnetic and is referred to as a high spin complex.

What is the geometry of NIC and 42?

[Ni(CN)4]2- is a square planar geometry formed by dsp2 hybridisation and not tetrahedral by sp3. [Ni(CN)4]2- is diamagnetic, so Ni2+ ion has 3d8 outer configuration with two unpaired electrons.

Why is NiCl4 2 paramagnetic?

The presence of CO ligand, which is a strong ligand, can pair all electrons in Ni(CO)4 and thus it is diamagnetic in nature but Cl− is a weak ligand and is unable to pair up the unpaired electrons and thus [NiCl4]2− is paramagnetic in nature.

Is NiCl4 2 paramagnetic or diamagnetic?

Solution. The compound, [NiCl4]2−, is paramagnetic since it contains two unpaired electrons.

Is feco5 paramagnetic?

It is paramagnetic and low spin complex.

Why is ptcl4 square planar?

A strong repulsion with the electron and ligand take place in between the platinum which leads to a strong crystal field splitting. Thus, the splitting breaks the degeneracy of dx2-y2 and dz2. This degeneracy stabilizes more to the square planar arrangement than the tetrahedral.

Why do square planar complexes form?

Crystal field stabilization is applicable to the transition-metal complexes of all geometries. The reason that many d8 complexes are square-planar is the very large amount of crystal field stabilization that this geometry produces with this number of electrons.

What is the difference between tetrahedral and square planar?

In tetrahedral molecular geometry, a central atom is located at the center of four substituents, which form the corners of a tetrahedron. In square planar molecular geometry, a central atom is surrounded by constituent atoms, which form the corners of a square on the same plane.
