Abstract

Abstract : An innovative, easy, fast, one-pot, completely wet-chemistry approach has been used for the synthesis and isolation of nanowires (NWs) of a spin-crossover iron(ii ) complex. Abstract : In this study, a simple, fast, one-pot approach for the isolation of nanowires (NWs) in coordination chemistry is reported. Nanowires (NWs) of spin-crossover (SCO) materials are extremely rare. Here, an innovative and easy synthetic process was developed to prepare NWs of a switchable polymorph of the known complex trans -[Fe(NCS)2 (abpt)2 ] using a wet-chemistry approach for the first time; abpt is the bidentate chelating ligand 4-amino-3, 5-bis(pyridin-2-yl)-1, 2, 4-triazole. The remarkable smoothness of the high-spin to low-spin transition, monitored through variable-temperature (300–80 K) Raman microscopy, compared with the sharp transition exhibited by the polycrystalline material, demonstrates the effect of the topological properties on the physical phenomena of the system.
