CONSIDERATIONS
Commonly,
the number of ligands associated
with a particular metal ion falls in the range 2 to 6.
• The coordination
number of a metal ion is numerically equal to the number of donor atoms (from the ligands) attached to the metal ion.
Coord. no. = no. of donor atoms
Coord. no. = no. of donor atoms
eg. the coordination number
of copper(II) in [Cu(NH3)4]2+ is four ( 4
x coord. N atoms)
