Answer:

The total number of points of attachment to the central element is called the coordination number.

 This can vary from 2 to as many as 16, but is usually 6.

 The coordination number of a complex is affected by:

·         Relative sizes of the metal ion

·         Ligands &

·         Electronic factors, such as charge

Complexes with coordination number 8

·         Dodecahedron (D2d) Geometry

·         Cube (Oh) Geometry

Complexes with coordination number 9

·         Three-face centered trigonal prism (D3h) Geometry

Complexes with coordination number 10

·         Bicapped square antiprism (D4d) Geometry
