Homometallic 2D Cd²⁺ and Heterometallic 3D Cd²⁺/Ca²⁺, Cd²⁺/Sr²⁺ Metal-Organic Frameworks Based on an Angular Tetracarboxylic Ligand.

ABSTRACT: This study reports on the synthesis, structural characterization and gas sorption studies of a homometallic 2D Cd²⁺ MOF and two heterometallic 3D Cd²⁺/Ca²⁺ and Cd²⁺/Sr²⁺ -MOFs based on the angular tetracarboxylic ligand 3,3',4,4'-sulfonyltetracarboxylic acid (H₄STBA). The homometallic 2D Cd²⁺ MOF with the formula [NH₂(CH₃)₂]⁺₂[Cd(STBA)]^2-_n·nDMF·1.5nH₂O-(1)_n·nDMF·1.5nH₂O was synthesized from the reaction of CdCl₂·H₂O and 3,3',4,4'-diphthalic sulfonyl dianhydride (3,3',4,4'-DPSDA) with stoichiometric ratio of 1:1.3 in DMF/H₂O (5/2 mL) at 100 °C. The two heterometallic
