Limitations of space preclude a comprehensive survey of the coordination chemistry of minerals. The reader is referred to the general references in this section for more information. Naturally, many other examples might have been chosen to exemplify various coordination numbers, geometries and complexes found in minerals. Nevertheless, the various species mentioned above do indicate the wide range of coordination chemistry in the solid state found in the mineral kingdom and the complexity of coordination compounds in the natural environment. 

Note More complex three-dimensional ionic structures are known where the A and/or B atoms are not all in equivalent sites having the same coordination numbers/ geometries. 

Oxidation state Coordination number Geometry Examples... 

Besides the possibility of charge modification, there can be some other consequences of the formation of metal ion complexes including dramatic changes in solubility, color, standard potential, coordination number, geometry, stereochemistry, magnetic susceptibility, and reactivity.
