AX4 geometry in coordination comppounds

Postby Vincent Leong 2B » Fri Dec 06, 2019 3:53 pm

When transition metal complexes have a coordination number of 4 or the coordination compound generally has this AX4 geometry, do we refer to the shape as "square planar or tetrahedral" or simply "tetrahedral" or "square planar"? If it's the latter, how can we differentiate between square planar and tetrahedral?

AX4 is for tetrahedral molecules. Square planar molecules have four bonding regions and two sets of lone pairs, or AX4E2.

AX4 only stands for Tetrahedral, Square Planar is AX4E2.
