This compound is an early example of a one-dimensional coordination polymer, serving as a representative structure for studies in solid-state physics.

The deep red color of the double salt, where the components were colorless, piqued the interest of early inorganic chemists and ultimately inspired studies into the physical properties of the compound in search of potential applications.

With no known case of plato-tetrammine isomerism at the time, this prompted extensive discussion in the literature of the true nature and properties of Wolffram’s Red Salt.

[4] In 1960, the crystal structure was shown to be consistent with the formulated double salt,[5] inspiring examinations of other analogues to compare and better understand this unique coordination pattern.

[6][7][8][9][10] Solid-state physical examinations were conducted to further elucidate the charge transfer across the mixed valence chain and potentially find use as semiconductors.
