Preparation, crystal structure and antibacterial performance of two transition metal carbacylamidophosphates complexes.

Preparation, Crystal Structure and Antibacterial Performance of Two Transition Metal Carbacylamidophosphates Complexes. [Display omitted] • Two transition metal complexes based on carbamidophosphate ligand were prepared by the simple solvent evaporation method. • The antibacterial test shows that both the ligand and the complex had certain antibacterial activity. Compounds with carbacylamidophosphates (CAPh) structures exhibited strong coordination abilities due to its heteroatoms such as O, N, and P. After coordinated with metal ions, the complexes usually show good antibacterial activity. Alfalfa is known as the vanguard for soil conservation and the crown of herbage. White hypha disease caused by Sclerotium rolfsii Sacc has become a major disease in yield decrease. However, there are relatively few researches on the treatment white hypha disease with complexes. Based on this, two Fe(III) and Cu(III) complexes based on CAPh structure were synthesized in this study, their crystal structures were determined by single crystal X-ray diffraction, and physicochemical properties were characterized by powder X-ray diffraction, thermogravimetry, Fourier transform infrared spectroscopy, etc. The antibacterial test shows that complexes has good activity for Sclerotium rolfsii Sacc, and the complexes usually exhibit better antibacterial activity than ligands. The antibacterial activity of MFL-Fe at 20 mg/mL is as high as 49.49 %. This provides a certain reference for treatment of alfalfa powdery mildew with complexes. [ABSTRACT FROM AUTHOR]
