摘要: We present a comprehensive study of the synthesis, heat capacity, crystal structures, UV–vis−NIR and mid-IR spectra, DFT calculations, magnetic electrical properties one-dimensional (1D) rhodium(I)–semiquinonato complex, [Rh(3,6-DBSQ-4,5-(MeO)2)(CO)2]∞ (3), where 3,6-DBSQ-4,5-(MeO)2•– represents 3,6-di-tert-butyl-4,5-dimethoxy-1,2-benzosemiquinonato radical anion. The compound 3 comprises neutral 1D chains complex molecules stacked in staggered arrangement with short Rh–Rh distances 3.0796(4) 3.1045(4) A at 226 K exhibits unprecedented bistable multifunctionality respect to its conductive temperature range 228–207 K. observed bistability results from thermal hysteresis across first-order phase transition, transition accompanies exchange interchain C–H···O hydrogen-bond partners between semiquinonato ligands. strong overlaps lead unusually ferromagnetic interactions in...
