We're being asked to draw the distribution of electrons for the central atoms in the following molecules using crystal field theory.Recall the energy splitting for each geometry.For octahedral complexes:For tetrahedral complexes:For K3[Cr(C2O4)3]•3H2O (octahedral):[readmore]• we can ignore the H2O• the coordination complex K3[Cr(C2O4)3] breaks up into:   K3[Cr(C2O4)3]         →        3 K+        +        [Cr(C2O4)3]3-coordination complex     counterion           complex ion• the metal in the complex ion is chromium and the ligand is C2O42-, therefore the charge of chromium is +3• the electron configuration of Cr3+ is 1s22s22p63s23p63d3• d3 → 3 electronsThe distribution of electrons for the central atom in K3[Cr(C2O4)3]•3H2O is:For K2[Cu(C2O4)2]•2H2O (tetrahedral):• we can ignore the H2O• the coordination complex K2[Cu(C2O4)2] breaks up into:   K2[Cu(C2O4)2]         →        2 K+       +      [Cu(C2O4)2]2-coordination complex     counterion           complex ion• the metal in the complex ion is copper and the ligand is C2O42-, therefore the charge of copper is +2• the electron configuration of Cu2+ is 1s22s22p63s23p63d9• d9 → 9 electronsThe distribution of electrons for the central atom in K2[Cu(C2O4)2]•2H2O is:
