Abstract

Abstract: A one‐dimensional (1D) coordination polymer [Co(btca)1/2 (mbpy)]n (1, mbpy =4, 4′‐Dimethyl‐2, 2′‐bipyridyl, H4 btca =1, 2, 4, 5‐Benzenetetracarboxylic acid) constructed by a mixed tetracarboxylic‐dipyridyl ligand strategy with a ribbon topology was synthesized and magnetically characterized. Magnetic studies combined with theoretical calculations reveal large easy‐axis magnetic anisotropy of the central Co(II) ions in a highly distorted five‐coordination geometry. Interestingly, field‐induced single‐ion magnet (SIM) behavior was evidenced in the chain compound, making the cobalt(II) coordination ribbon to be the first five‐coordinate SIM chain. Abstract : A one‐dimensional coordination polymer with five‐coordinate cobalt(II) centers and a ribbon topology was reported to show field‐induced single‐ion magnet behavior.
