Synthesis, Structural Characterization, and Water Vapor Sorption Behavior of Two Ligand Ratio-Dependent Supramolecular Networks, [Cd(2,2'-bpym)_1.5(BDC)]·0.5(2,2'-bpym)·5H₂O and [Cd(2,2'-bpym)_0.5(BDC)(H₂O)₃].

ABSTRACT: Two ligand ratio-dependent supramolecular networks, [Cd(2,2'-bpym)_1.5(BDC)]·0.5(2,2'-bpym)·5H₂O (1) and [Cd(2,2'-bpym)_0.5(BDC)(H₂O)₃] (2), (BDC^2- = dianion of terephthalic acid and 2,2'-bpym = 2,2'-bipyrimidine) have been synthesized and structurally characterized by the single-crystal X-ray diffraction method. Structural determination reveals that compound 1 is a two-dimensional (2D) layered metal-organic framework (MOF) constructed via the bridges of Cd(II) ions with 2,2'-bpym and BDC^2- ligands, and compound 2 is a zero-dimensional (0D) 2,2'-bpym-bridged di-Cd(II) monomeric complex. When the thermally dehydrated powders of 1 (at 100 °C) were immersed into water solution,
