Synthesis, structure and magnetocaloric properties of a new two-dimensional gadolinium(III) coordination polymer based on azobenzene-2,2′,3,3′-tetracarboxylic acid
Abstract:A new Gd3+ coordination polymer (CP), namely, poly[diaqua[μ4-1′-carboxy-3,3′-(diazene-1,2-diyl)dibenzene-1,2,2′-tricarboxylato]gadolinium(III)], [Gd(C16H7N2O8)(H2O)2]
n
, (I), has been synthesized hydrothermally from Gd(NO3)3·6H2O and azobenzene-2,2′,3,3′-tetracarboxylic acid (H4abtc). The target solid has been characterized by single-crystal and powder X-ray diffraction, elemental analysis, IR spectroscopy and susceptibility measurements. CP (I) crystallizes in the monoc… Show more
“…45–49 The −Δ S m (7 T) of 1 is similar to the reported 2D compounds, with values that range from 27 J K −1 kg −1 (ref. 50) to 49.29 J K −1 kg −1 . 51…”
Gd complexes have been studied as magnetic coolant due to their large magnetic anisotropy. In this work we present a Gd 2D MOF of formula [Gd(MeCOO)(PhCOO)2] (1). We characterize the...
