Syntheses, structures, photoluminescent and electrochemical properties of two ferrocenylthiocarboxylate-containing complexes

Two one-dimensional metal–organic complexes containing ferrocenylthiocarboxylate components, [M(η2-SOCFc)2(btx)]n (M = Ni, 1, Co, 2; Fc = (η5-C5H5)Fe(η5-C5H4); btx = 1,4-bis(triazol-1-ylmethyl)benzene), have been synthesized and structurally characterized. X-ray crystal structural analyses reveal that the two complexes are isomorphous. Both of them exhibit interesting topological motif: 1-D sine curve chain structure. Photoluminescent studies suggest that the two complexes and the ligand FcCOSNa all exhibit broad fluorescence signals with the emission maxima at approximately 390 nm. Electrochemical studies show that the half-wave potentials of the ferrocenyl moieties in 1 and 2 have deviations relative to the free FcCOSNa ligand. Additionally, using quantum chemistry calculations, we further analyzed their luminescent and electrochemical behaviors.
