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

The synthesis, crystal structure, thermal stability, porosity and magnetic properties of three new layered coordination polymers [(M 2 ( p Q) 3 )·4DMAA] n (M 3+ = La 3+ ( 1 ), Pr 3+ ( 2 ), Nd 3+ ( 3 ); p Q 2− - 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. 2D-coordination redox-active networks bearing t -Bu-substituted anilic bridged ligands and lanthanide ions were synthesized and characterized.
