What is the structure of Co Co 4?
Structure and properties HCo(CO)4 adopts trigonal bipyrimidal structure with the equatorial CO ligands slightly bent out of the equatorial plane. The hydride ligand occupies one of the axial positions, thus the symmetry of the molecule is C3v.
What hybridization is in Ni Co 4?
The empty 4s and three 4p orbitals undergo sp3 hybridization and form bonds with CO ligands to give Ni(CO)4. Thus Ni(CO)4 is diamagnetic. * All of these 10 electrons are pushed into 3d orbitals and get paired up when strong field CO ligands approach Ni atom.
What is the geometry of cocl4 2?
tetrahedral structure
The [CoCl4]2- complex ion is experimentally known to have a tetrahedral structure.
What is the hybridisation of CO NH3 6?
d2sp3
In [Co (NH3)6]3+, Co is in +3 oxidation state with the configuration 3d6. In the presence of NH3 a strong ligand, the 3d electrons pair up leaving two d-orbitals empty. Hence, the hybridization is d2sp3 forming an inner orbital octahedral complex.
What is the hybridization of CoCl4 2?
The ligands occupy one d orbital, one s orbital and 2 p orbitals. Thus the hybridisation is “dsp2” with “square planar” geometry. It is “paramagnetic” and is a “low spin complex”.
What is the hybridisation of [Co(CO) 4] 4+?
The hybridisation of [Co (CO)4]+ would be dsp2. Cobalt has electronic configuration [Ar]3d7 4s2. And here the oxidation state of cobalt is +1; so the configuration would be 3d7 4s1. Now carbonyl is the strongest ligand and hence it will attract even electrons in the s orbital and pairing will take place.
What is the hybridization of Nini(CO)4?
Ni (CO)4 is tetrahedral and contains sp3 hybridized Ni atom. Ni forms octahedral paramagnetic [Ni (NH3)6]2+ ( two unpaired electrons) as well as diamagnetic planar [Ni (NH3)4]2+ complexes.
What is the hybridization of carbon and oxygen in carbon monoxide?
For Carbon, we have one lone pair of electrons and one atom ( Oxygen) attached to it. Molecules having steric number 2 have sp hybridization. This will also hold true for Oxygen. Thus, the hybridization of both Carbon and Oxygen atoms in the Carbon Monoxide molecule is sp.
What is the hybridisation of CN in cobalt-cobalt ion?
Therefore, as CN is a strong ligand it makes the unpaired electrons of cobalt to pair up and occupies the space. The ligands occupy one d orbital, one s orbital and 2 p orbitals. Thus the hybridisation is “dsp2” with “square planar” geometry. It is “paramagnetic” and is a “low spin complex”.
