Abstract
A robust and low dielectric 3D metal-organic framework [Mg(phen)(bdc)]n (1; phen = 1,10-phenanthroline, bdc2- = 1,4-benzenedicarboxylate) was hydrothermally synthesized from magnesium acetate, H2bdc, and phen ligands. Compound 1 has a non-interpenetrated network with an uncommon cds-type topology. Chemical and dielectric investigations of this material indicate that it retains a high chemical stability and has a low dielectric constant of 3.33±0.1 (at 100 kHz), which is the lowest value for Mg-based MOFs reported to date. In addition, temperature-dependent dielectric studies revealed that its low dielectric constant is retained over a wider temperature range. Mg-based MOFs have the advantage of being a new class of dielectric materials because of their many intrinsic properties.
