2D-metal–organic coordination polymers of lanthanides (La(iii), Pr(iii) and Nd(iii)) with redox-active dioxolene bridging ligands

Abstract

The synthesis, crystal structure, thermal stability, porosity and magnetic properties of three new layered coordination polymers [(M₂(pQ)₃)·4DMAA]_n (M³⁺ = La³⁺ (1), Pr³⁺ (2), Nd³⁺ (3); pQ²⁻ – the dianionic form of 2,5-dihydroxy-3,6-di-tert-butyl-para-quinone; DMAA = N,N′-dimethylacetamide) are reported. The coordination polymers obtained were investigated by solid-state electrochemistry which demonstrates multistep one-electron transformations caused by the presence of redox-active dioxolene ligands.
