Metal complexes (already in extensive use today by nature and human) can give some inspiration how metal atoms could be integrated in [[diamondoid metamaterial|future atomically precise structures]].

Metal complexes have usually strong covalent character avoiding [[the problems of metallic bonds]].

* Coordination complexes with their ligands not mutually linked together can show optimal coordination geometries.
* Chelate complexes can be seen as examples of bond networks that are suitable to weakly restrain the various fingers to a configuration space matching the metal to be chelated. <br>The bonds are not holding the fingers in (fully) place since single sigma binds can rotate and long chains of double bonds can flex. <br>The weak restraint can be seen as a increase in "[[effective concentration]]".

Geometries from these examples both metal-to-ligand from the simple complexes and ligand-to-ligand bonds from the chelates can be used for the design of foldamer structures or diamondoid structures that match these geometries. Those though can have much higher [[stiffness]] while still being simple (compact and highly symmetry) unlike many natural proteins.

Periodic lattices of compact complexes can be seen as a transition to [[gemstone like compound]]s.

Metal complexes often have strong colors (pigments) so one possible reason to include them could be to [[color emulation|give products color]]. <br>Complexes containing very common elements like e.g. [[iron]] can be used as structural building material.
