Bistable Hofmann-Type Fe^II Spin-Crossover Two-Dimensional Polymers of 4-Alkyldisulfanylpyridine for Prospective Grafting of Monolayers on Metallic Surfaces.

ABSTRACT: Aiming at investigating the suitability of Hofmann-type two-dimensional (2D) coordination polymers {Fe^II(L_ax)₂[M^II(CN)₄]} to be processed as single monolayers and probed as spin crossover (SCO) junctions in spintronic devices, the synthesis and characterization of the M^II derivatives (M^II = Pd and Pt) with sulfur-rich axial ligands (L_ax = 4-methyl- and 4-ethyl-disulfanylpyridine) have been conducted. The thermal dependence of the magnetic and calorimetric properties confirmed the occurrence of strong cooperative SCO behavior in the temperature interval of 100-225 K, featuring hysteresis loops 44 and 32.5 K/21 K wide for Pt^II-methyl and Pt^II/Pd^II-ethyl derivatives, while
