SUMMARY

The discussion focuses on the coordination number of copper(I) in the complex [Cu(P(C6H5)3)3]+, which is 3 due to the interaction of lone pairs from phosphine ligands with the empty 4p orbitals of copper. Copper in this state has a +1 charge and an electron configuration of [Ar] 4s0 3d10. The formation of bonds occurs between the lone pairs on the phosphorus atoms and the available orbitals on the copper atom, while the 4s orbital remains unoccupied in this scenario. Additionally, methods for determining coordination numbers in metal-ligand complexes are sought for further understanding.

PREREQUISITES
  • Understanding of coordination chemistry

For metals like copper(I), how does it have a coordination number of 3 in some compounds like [Cu(P(C6H5)3)3]+. I've learned that these coordination bonds are formed by interacting lone pairs from ligands and empty orbitals on the central metal atom. In this case, copper has a 1+ charge and configuration of [Ar] 4s0 3d10 and I'm just slightly confused on how it would form 3 bonds...
Would new bonds just be formed between the lone pair on each phosphorous and the 3 4p orbitals from copper? What happens to the 4s orbital in this case?

If there's a method to determine the coordination number of a metal with ligands, could you please expand on that as well or refer me to any sources?

Thanks!
