1D MnIII–FeII heterometallic coordination polymer built by an approach of metalloligand

1D heterometallic coordination polymer of [(FeII(L)2)(MnIII(salen))(ClO4) · 2CH3CN · CH3OH] (1 · 2CH3CN · CH3OH) has been built through a metalloligand approach (L = hydrotris (1,2,4-triazolyl)borate). Ferrous [FeII(L)2] moiety can be easily incorporated into further extended networks by the facile reduction of ferric antiprismatic [FeIII(L)2]+ metalloligand due to the reducing ability of borate ligands during the reaction. And more, hydroquinone facilitates the reduction. Therefore, we present single crystal X-ray structure analysis of 1 · 2CH3CN · CH3OH along with X-ray absorption spectroscopy to confirm the reduction of iron centres.
