Cadmium Iodide Complex with 4-Aminomethylbenzoic Acid: Synthesis, Crystal Structure, and Luminescent Properties
[СdI2(4-АmbaH)2] · H2O has been synthesized by the reaction between CdI2 and 4-aminomethylbenzoic acid (4-AmbaH) in an aqueous solution. According to X-ray diffraction data, a 4-AmbaH aromatic molecule crystallizes in the form of a zwitterion with protonation of the NH 3 + amino group and deprotonation of the carboxylate group, which is chelately coordinated to the Cd2+ ion. In addition to two iodine atoms, the Cd2+ atom located on the double crystallographic axis is coordinated to the chelate carboxylate O(1) and O(2) atoms of two crystallographically equivalent ligands 4-AmbaH. The octahedral geometry of the Cd2+ ion is strongly distorted due to the chelate addition of 4-AmbaH. The chelate coordination of COO–groups is confirmed by IR spectroscopy data. The complex has luminescent properties.
