Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5-Hydroxynicotinic acid, is researched, Molecular C6H5NO3, CAS is 27828-71-3, about Six-Coordinate Lanthanide Complexes: Slow Relaxation of Magnetization in the Dysprosium(III) Complex.Formula: C6H5NO3.
A series of six-coordinate lanthanide complexes {(H3O)[Ln(NA)2]·H2O}n (H2NA = 5-hydroxynicotinic acid; Ln = GdIII (1·Gd); TbIII (2·Tb); DyIII (3·Dy); HoIII (4·Ho)) have been synthesized from aqueous solution and fully characterized. Slow relaxation of the magnetization was observed in 3·Dy. To suppress the quantum tunneling of the magnetization, 3·Dy diluted by diamagnetic YIII ions was also synthesized and magnetically studied. Interesting butterfly-like hysteresis loops and an enhanced energy barrier for the slow relaxation of magnetization were observed in diluted 3·Dy. The energy barrier (Δτ) and pre-exponential factor (τ0) of the diluted 3·Dy are 75 K and 4.21 × 10-5 s, resp. This work illustrates a successful way to obtain low-coordination-number lanthanide complexes by a framework approach to show single-ion-magnet-like behavior.
