Hybrid organic-inorganic connectivity of NdIII(pyrazine-: N, N ′-dioxide)[CoIII(CN)6]3- coordination chains for creating near-infrared emissive Nd(iii) showing field-induced slow magnetic relaxation

A near-infrared emissive and magnetically anisotropic Nd(iii) complex is formed within a hybrid organic-inorganic {[NdIII(pzdo)(H2O)4][CoIII(CN)6]}·0.5(pzdo)·4H2O (1) (pzdo = pyrazine-N,N′-dioxide) ladder chain built of coexisting Nd-pzdo-Nd and Nd-NC-Co molecular bridges. 1 reveals two NdIII-centered properties, a field-induced slow magnetic relaxation of a single-ion origin with a thermal energy barrier of ΔE/kB = 51(2) K at Hdc = 1 kOe, and a near-infrared fluorescence sensitized by organic and inorganic linkers.

Oxidation methods for aromatic diazines: Substituted pyrazine-N-oxides, pyrazine-N,N′-dioxides, and 2,2′:6′,2″-terpyridine-1,1″-dioxide

In the course of investigations into the intermolecular interactions of azaaromatic N-oxides it was necessary to perform oxidations of the pyridine and pyrazine moieties. Generally, it was found that direct oxidation with OXONE gave efficient preparation of pyrazine dioxides. Oxidation with dimethyldioxirane was used to preclude problems associated with the isolation of particularly hydrophilic pyrazine and pyrazine-N-oxides.
