Abstract
![]()
Three copper(II)/mesoxalate-based MOFs with formulas
(H3O)[Cu9(Hmesox)6(H2O)6Cl]·8H2O (1), (NH2Me2)0.4(H3O)0.6[Cu9(Hmesox)6(H2O)6Cl]·8H2O (2), and (enH2)0.25(enH)1.5[Cu6(Hmesox)3(mesox)(H2O)6Cl0.5]Cl0.5·5.25H2O (3) were synthesized (H4mesox = mesoxalic
acid = 2,2-dihydroxypropanedioic acid, en = ethylenediamine). Essentially,
all of the compounds display the same anionic network with a different
arrangement of the cations, which have a remarkable effect on the
proton conduction of the materials, ranging from 1.16 × 10–4 S cm–1 for 1 to 1.87
× 10–3 S cm–1 for 3 (at 80 °C and 95% RH). These compounds also display antiferromagnetic
coupling among the copper(II) ions through both the carboxylate and
alkoxido bridges. The values of the principal magnetic coupling constants
were calculated by density functional theory (DFT), leading to congruent
values that confirm the predominant antiferromagnetic nature of the
interactions. Three copper(II)-mesoxalate
metal−organic frameworks
were synthesized in the presence of three different cations: hydronium,
dimethylammonium, and ethylenediammonium, which neutralize the charge
of the anionic networks. Besides the crystallographic characterization
and the investigation of the magnetic properties, the compounds show
varying proton conductivities depending on the included cations. The
proton conductivity increases 1 order of magnitude in the case of
compound 3 (1.87 × 10−3 S cm−1 at 80 °C and 95% RH), which contains ethylenediammonium
cations.
