4-COORDINATE COMPLEXES
Four-coordinate complexes:
•
Square planar complexes
possess either
a plane of symmetry, a 2-fold rotation axis
or are superimposable and therefore
will not be chiral.
•
Tetrahedral complexes
will be
chiral if
all ligands are different.
eg.
[Zn(H
2
O)(NH
3
)(OH)Cl]
Square plane is plane of symmetry in MABCD
