Square planar are special cases of complexes with CN=6.
However, in square planar, in the structure- the ligands at the top and bottom of the octahedron are further from the central metal ion. Therefore they are not counted as “nearest neighbours”, so the CN=4 instead of 6.
The four nearest ligands form the square that you can see in the octahedron.
Arrangement of ligands in octahedron and the square planar make
STERO ISOMERISM possible.
Stero-isomers
The atoms (or ions) form the same bonds but cannot be superimposed. They have different arrangements in space.
oohh god- old chemistry work was sending it to a friend since hes doing my course next year.
