FREE Expert Solution

A coordination complex consists of a metal atom or ion at the center surrounded by lone pair donors called ligands.

Coordination number is the number of atoms/ions immediate to the center metal atom/ion in a complex.

The formula for a complex is written in the following syntax:

[M(L)n]x

Where,

M = metal
L = ligand
n = number of ligands
x = charge on complex (can be 0)
