What Is The Hybridization Of Ni In Ni(CN)3?

The hybridization of Ni in Ni(CN)3 is sp2. In this compound, the nickel atom is bonded to three cyanide ions (CN-), which act as ligands. Each ligand donates a lone pair of electrons to the Ni atom, forming three sigma bonds. This results in the formation of a trigonal planar geometry around the Ni atom. To accommodate this geometry, the Ni atom undergoes sp2 hybridization, where the 4s and two of the 4p orbitals hybridize to form three sp2 orbitals that are oriented in a trigonal planar arrangement. The remaining 4p orbital remains unhybridized and perpendicular to the plane of the sp2 orbitals.
