Polynitrile anions as ligands: From magnetic polymeric architectures to spin crossover materials

Tris(2,2′-bipyridine)iron(II) bis(1,1,3,3-tetracyano-2-ethoxypropenide) dihydrate: chiral hydrogen-bonded frameworks interpenetrate in three dimensions

“…Organic polynitrile ligands have received considerable attention recently in the design of new molecular compounds exhibiting the spin crossover (SCO) phenomenon (Dupouy et al, 2008(Dupouy et al, , 2009Benmansour et al, 2010). Iron(II) complexes containing octahedral FeN 6 coordination are amongst the most studied SCO compounds and in such materials, control over co-operative SCO behaviour is still of major interest in this field.…”

1,1′-Diethyl-4,4′-bipyridine-1,1′-diium bis(1,1,3,3-tetracyano-2-ethoxypropenide): multiple C—H...N hydrogen bonds form a complex sheet structure

“…Polynitrile anions have recently received considerable attention in the fields of coordination chemistry and molecular materials (Benmansour et al, 2010). These organic anions are of interest for their ability to adopt various coordination modes with metal centres and for their high degree of electronic delocalization (Thé tiot et al, 2003;Benmansour et al, 2007Benmansour et al, , 2009Atmani et al, 2008;Setifi et al, 2007Setifi et al, , 2009Setifi et al, , 2010.…”

Crystal structure and characterization of two cadmium(II) coordination polymers with a multidentate N-donor tecton 3-(pyridin-4-yl)-5-(pyrazin-2-yl)-1H-1,2,4-triazole

“…[1][2][3][4][5]. Diverse network architectures and physicochemical properties for such crystalline solids essentially depend on the metal ions and organic ligands used in the synthetic processes.…”
