Abstract

Self-assembled hybrid supramolecular architectures formed between amphiphilic anions and long alkylated cationic cobalt(II) complexes of type [Co(C_n-terpy)₂](C₁₂-Glu)₂ (n = 15–20) have been synthesized and characterized by TEM, PXRD and magnetic susceptibility measurements. The hybrids display wire or rolled sheet supramolecular arrangements with odd and even alkyl chain dependence, with the cobalt(II) centres exhibiting gradual spin-crossover behaviours.
