Write the hybridization and magnetic behaviour of the complex [Ni(CO)4].
(At.no. of Ni = 28)
Carbonyl, CO being a strong field ligand causes the pairing of up valence electrons in the Ni atom against the Hund's Rule of Maximum Multiplicity. This results in the formation of an inner orbital complex, [Ni(CO)4] having diamagnetic character. [Ni(CO)4] has sp3 hybridization.
On the basis of crystal field theory, write the electronic configuration for d4 ion if ∆o < P ?
A coordination compound has the formula CoCl3.4NH3. It does not liberate ammonia but forms a precipitate with AgNO3. Write the structure and IUPAC name of the complex compound.
