Five novel complexes [Co₂(BCTA)(H₂O)₄]_n (1), [Co₂(BCTA)(Phen)₂(H₂O)₂] (2), [Co₂(BCTA)(Bipy)₂(H₂O)₂] (3), [Cu₂(BCTA)(Bipy)₂(H₂O)₂]_n (4), and [Cd₂(BCTA)(Bipy)₂(H₂O)₂]_n (5) (H₄BCTA=2,5-bis(carboxymethoxy)terephthalic acid, Phen=1, 10-phenanthroline, Bipy=2, 2′-bipyridine) were synthesized by solvothermal condition. All complexes were structurally characterized by infrared spectroscopy, elemental analysis, thermogravimetric analysis, and single-crystal X-ray diffraction. Complexes 2 and 3 have zero-dimensional structures, complex 5 has a 1D banded structure, and complexes 1 and 4 have 2D network structures. Hirshfeld surface analysis of complexes 1-5 was performed, and antifungal activities of the complexes were investigated. Complex 5 exhibited super-strong antifungal activity against seven pathogenic fungi, with all inhibitory rates reaching 100%.
