Large differences in the conductive properties of alkylamino derivatives of Magnus' green salt, [Pt(NH2R)4][PtCl4], parallel their dramatic color differences and thermochromism (see Figure, R = 2-ethylhexyl). Both phenomena are related to the intracolumnar Pt–Pt distance, d, with the one-dimensional charge mobility increasing inversely with d, from less than 0.001 cm2 V–1 s–1 for d ≈ 3.6 Å up to ≥ 0.060 cm2 V–1 s–1 for d ≈ 3.1 Å.
