Web3. Our teacher told us this trick to tell if complex is going to be square planar. We are considering the fact that the coordination no. is 4. If the metal has a d X 7, d X 8 or d X 9 configuration along with a strong field ligand or d X 4 with weak field ligand then complex will be square planar otherwise tetrahedral. WebExamples for anionic ligands are F –, Cl –, Br –, I –, S 2–, CN –, NCS –, OH –, NH 2– and neutral ligands are NH 3, H 2 O, NO, CO. A ligand is an ion or molecule, which binds to the central metal atom to form a …
