Linear chain compound

[1][2] Many linear chain compounds feature square planar complexes.

[5] In contrast to linear chain compounds, extended metal atom chains (EMACs) are molecules or ions that consist of a finite, often short, linear strings of metal atoms, surrounded by organic ligands.

[8][9][10] Linear chains of Pd-Pd bonds protected by a "π-electron sheath" are known.

[1][11] Not only do these olefin-stabilized metal chains constitute a significant contribution to the field of organometallic chemistry, both the complex's metal atom structures and the olefin ligands themselves can conduct a current.

The technique is used to obtain single crystals of low-dimensional electrical conductors.
