Coordination Number and Geometrical Shape

COORDINATION NUMBER and THE COMPLEX's GEOMETRICAL SHAPE


What is a Coordination Number
٭ The coordination number is the total number of neighbours of a central atom in a molecule or ion (the number of donor atom).
٭ It is defined originally in 1893 by Alfred Werner.
٭ It was determined by simple counting the other atoms to which it is bonded (by either single / multiple bonds).


What is Geometrical Shape?
٭ Geometrical shapes are the shapes resembling or employing the simple rectilinear or arviliner lines/figures used in geometry.
٭ In this case, the complex formed has 4 coordination numbers, in which the possible geometrical shape is tetrahedral or square planar.
٭ The DMPS bind with mercury which is one of transition metal element. So, the geometrical shape is definitely a square planar.

Overall,
When DMPS binds with mercury, it formed complex with 4 coordination numbers and has the geometrical shape of a square planar.
