Polymeric delta-MgCl2 nanoribbons

摘要

delta-MgCl2 has relevant applications in the field of electrochemical energy storage and Ziegler-Natta catalysis. Here, we clarify the short-range structural peculiarities that make the disordered phase delta-MgCl2 extremely chemically active relative to the higher lattice energy phases, alpha-MgCl2 and beta-MgCl2, X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS) and nuclear magnetic resonance (NMR) results are included. These findings, demonstrate the existence Of [MgCl2](n) nanoribbons and active nanosurfaces in delta-MgCl2 and provide new insight about the nature of the bonding in the allotropic forms Of MgCl2.
