Pt II COMPLEXES ARE SQUARE PLANAR IRRESPECTIVE OF WEAK OR STRONG LIGANDS? WHY?
Dear student, (PtCL4)2- has square planar geometry because it has 4 bonds and 2 lone pairs of electrons. Pt is one of those strange elements like S and P that has 6 regions of high electron density. Look at it like this: Draw Pt in the center, and put 4 Cl around it. Now each Cl comes in with 7 electrons and Pt comes in with 6. Because there is a -2 charge you add two more electrons. So now you have each Cl bonded to Pt with a single bond which means 2 electrons. Now you have 4 extra electrons which means 2 lone pairs. Please feel free to ask your queries here. We are all IITians and here to help you in your IIT JEE preparation. All the best. Win exciting gifts by answering the questions on Discussion Forum.
