Is CU NH3 4 SO4 square planar?

Is CU NH3 4 SO4 square planar?

Since −NH3​ is a strong field ligand, it will form square planar complex with Cu2+ with dsp2 hybridization.

What is the oxidation number of Cu NH3 4 SO4?

In [ Cu ( NH3)4]SO4 , the oxidation number of NH3 is zero (0) because the ammonia molecule is a neutral molecule . On the other hand the oxidation number of SO4 ion is –2 . Now, let the oxidation number of Cu is ‘X’ . Therefore, the summation of total oxidation number of the complex compound should be zero .

What is the difference between sp2 and dsp2?

So, the electron pairs of the ligands occupy the one d orbital, next s orbital and then 2 p orbitals. So, they are called dsp2 hybrid orbitals. On the other hand for sp3, no such pairing takes place. You decide within the two by looking at the strength of the ligand.

Is CL a weak field ligand?

Weak field ligands induce less splitting of the crystal fields. They form complexes with high spins. Examples: chloride ions, fluoride ions etc. Strong field ligands result in greater splitting of the crystal field.

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.

Why CN is an Ambidentate ligand?

This type of ligand, capable of sharing 1 pair of electrons, is referred to as a monodentate ligand. Ethylenediamine (1,2 diaminoethane) has two lone pair of electrons that may be shared with a metal atom or ions. Common ambidentate ligands include cyanide (CN-), nitrite (NO2 -), thiocyanate (SCN-). 2.

Is Ambidentate a ligand?

Ambidentate ligand is a type of ligands which have the ability to bind to the central atom via the atoms of two different elements. Examples: thiocyanate ion(NCS–) which can bind to the central metal atom or ion with either nitrogen or sulfur atoms.

Is EDTA an Ambidentate ligand?

EDTA, a hexadentate ligand, is an example of a polydentate ligand that has six donor atoms with electron pairs that can be used to bond to a central metal atom or ion. Unlike polydentate ligands, ambidentate ligands can attach to the central atom in two places.

What is the difference between Ambidentate ligand and chelating ligand?

Ligand which can ligate through two different atoms is called ambidentate ligand. When di- or polydented ligand uses its two or more donor atoms to bind a single metal ion, it is said to be chelating ligand.

What is the difference between a chelate and ligand?

Many ligands are capable of binding metal ions through multiple sites, usually because the ligands have lone pairs on more than one atom. Ligands that bind via more than one atom are often termed chelating. A ligand that binds through two sites is classified as bidentate, and three sites as tridentate.
