Question

How many moles of bidentate ligand react with 7.00 mmol of a cation that hydrolyzes at each of the following? a) sp3 b) dsp2 c) d2sp2

Answer 1

a) sp3 :coordination number = 4

for bidentate ligand coordination number = 2

M   +   2 en ----------------> complex

1           2

7.00      ?

bidentate ligands needed = 2 x 7 = 14

b) dsp2 : here also coordination number = 4

so :

bidentate ligands needed = 2 x 7 = 14

c) d2sp2 coordination number = 5

M + 2 en + monodentate ligand -----------> complex

1        2              1

7      14

bidentate ligands needed = 14
