Abstract

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.
