What is the coordination number of Cu in Tetraammine copper sulphate?
The IUPAC name of Cuprammonium sulfate is tetraamminecopper(II) sulfate. Now in this structure, there are four ammonia molecules directly attached with the copper. Therefore, the coordination number of copper in Cuprammonium sulfate is 4.
What is the oxidation number of Cu metal in Cu NH3 4 SO4?
Sulphate ion SO42– carries charge of -2, as NH3 carries no charge, therefore charge on copper is +2, i.e. oxidation number of copper is +2.
What is coordination number of Pt in Pt NH3 2cl2?
Generally, platinum has oxidation number+2 when its co-ordination number is 4 & it has oxidation number +4 when its co-ordination number is 6. In [math][Pt(NH_3)_4NO_2Cl]SO_4[/math], the co-ordination number of platinum is 6, so its oxidation number will be +4.
What is the coordination number of Pt in the coordination compound Pt NH3 4 2?
Coordination Compounds. What is coordination number of metal ion in [Pt(NH3)2(C2O4)]? In this complex the coordination number of metal ion is 4. such to two electron pair from diamine and 2 electron pair from oxalate (didentate ligand).
What is the oxidation number of platinum in ptcl2 NH3 2?
Now, charge on Cl = -2, NH3 = 0, therefore, -2 charge on Cl and +2 charge on the coordination sphere is balanced by +4 charge on Pt. Thus, the oxidation state of Pt is +4.
What is the coordination number of Al in K3 Al C2O4 3?

Why is the coordination number of NaCl 6?
It crystallizes into FCC lattice that is face centered cubic crystal. … In NaCl crystal, each sodium ion is surrounded by 6 chloride ions and each chloride ion is surrounded by 6 sodium ions. So, the coordination number of NaCl as per definition will be 6:6.
What is the coordination number of nickel in ni NH3 6 2+?
M.Sc chemistry. In the both cases, the co-ordination number of nickel is six with octahedral geometry. The oxidation number of nickel is +2 with 3d8 system. Crystal field theory requires the splitting of the degenerate d-orbitals with the approaching of the ligands.
What is the coordination number of CO NH3 6 cl3?
Hence the coordination no. of the given compound will be 6.
What is the coordination number of CO in CO NH3 3cl3?
coordination number depends on the no. of ligands attach to the central metal in the coordination sphere. so, 6 is correct answer hope it helps you, comment if any query.
