Verdazyl-lanthanide(III) one dimensional compounds: synthesis, structure and magnetic properties.
The first one-dimensional compounds where [Ln(hfac)(3)] (Ln = Gd, Tb, Dy) building blocks are bridged by a verdazyl-based radical, namely 3-imidazolyl-1,5-dimethyl-6-oxoverdazyl, were prepared and their structures elucidated; the magnetic properties were measured for all compounds and quantitatively fitted for Ln = Gd(III) using an alternate chain model leading to J(1) = -1.58 cm(-1) and to J(2) = -0.42 cm(-1).
