A one-dimensional π-d conjugated coordination polymer for sodium storage with catalytic activity in Negishi coupling

Abstract

p-d Conjugated coordination polymers (CCPs) have attracted muchattention for various applications,although the chemical states and structures of many CCPs are still blurry. Now,aone-dimensional (1D) p-d conjugated coordination polymer for high performance sodium-ion batteries is presented. The chemical states of the obtained coordination polymer are clearly revealed. The electrochemical process undergoes at hree-electron reaction and the structure transforms from C=Nd ouble bonds and Ni II to CÀNs ingle bonds and Ni I ,r espectively.Our unintentional experiments provided visual confirmation of Ni I .T he existence of Ni I was further corroborated by its X-raya bsorption near-edge structure (XANES) and its catalytic activity in Negishi cross-coupling.Supportinginformation and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.
