Compounds of s-Metals with Spin-Labeled Nitrophenol

A series of paramagnetic salts of s -elements (Li, Na, K, Rb, Cs) with deprotonated nitroxide radical, 2-(2-hydroxy-5-nitrophenyl)-4,4,5,5-tetramethyl-4,5-dihydro-1 H -imidazol-1-oxyl 3-oxide (L), were synthesized and isolated as crystals. According to X-ray diffraction data, these compounds are pol...

Description
Summary:A series of paramagnetic salts of s -elements (Li, Na, K, Rb, Cs) with deprotonated nitroxide radical, 2-(2-hydroxy-5-nitrophenyl)-4,4,5,5-tetramethyl-4,5-dihydro-1 H -imidazol-1-oxyl 3-oxide (L), were synthesized and isolated as crystals. According to X-ray diffraction data, these compounds are polymers of different dimensionality (CCDC nos. 2342497–2342506). As indicated by the results of quantum chemical calculations and magnetic measurements, weak antiferromagnetic exchange interactions predominate in the paramagnetic salts, with the interaction energy decreasing with increasing radius of the alkali metal ion.
