CRYSTAL STRUCTURE, AND BIOLOGICAL ACTIVITY OF A 2D Cd(II) COORDINATION POLYMER BASED ON 1-HYDROXY-2-NAPHTHOIC ACID

Аннотация

A new two-dimensional (2D) coordination polymer based on Cd (II) was synthesized in the presence of 4-hydroxy-1-naphthoic acid (HNA), acetic acid (AA), N, N-dimethylformamide (DMF), and cadmium acetate. The crystalline structure of the synthesized HNA-CP was determined using single-crystal X-ray diffraction, and it was found that the HNA and AA ligands are fluctually bound with Cd (II) centers in the inner coordination region, while two DMF molecules are located in the outer coordination region. As a result of structural analysis, a classical "oar wheel" type nucleus with a distorted quadratic-pyramidal geometry was identified due to bidentate bridge-forming ligands. Antifungal studies have shown that HNA-CP exhibits significant inhibitory activity against Fusarium oxysporum, F. solani, and F. graminearum. The obtained results confirm that HNA-CP is a promising multifunctional material.
