IR spectra of monosubstituted 1,4-dioxanes

Self‐assembly of Two 2D Copper(II) Coordination Networks with Tetrachloro‐1,3‐benzenedicarboxylate: Solvent Effects, Supramolecular Interactions, and Luminescence Behavior

“…Both complexes show characteristic bands of carboxylate groups appearing in the region of 1590–1660 cm –1 for the antisymmetric stretching vibrations and at 1340–1410 cm –1 for the symmetric stretching vibrations, respectively. For 2 , the strong characteristic peaks around 873 and 1120 cm –1 can be assigned to the ring valence vibrations of dioxane 30. In addition, the absence of strong adsorption band around 1712 cm –1 for the free 1,3‐H 2 BDC‐Cl 4 molecule indicates that the 1,3‐H 2 BDC‐Cl 4 ligand in 1 and 2 is completely deprotonated, which is consistent with the consideration of charge balance.…”

“…3) has been made ( Table 1) by comparison with the IR spectra of the free ligand H 3 bhmpc [61] and of 1,4-dioxane [62]. Upon complexation, the three n O-H bands found in the H 3 bhmpc ligand are replaced by a single large band centered at 3440 cm À1 (Dn 1/2 = 400 cm À1 ).…”
