Dianilineglyoxime Salt and Its Binuclear Zn(II) and Mn(II) Complexes with 1,3-Benzenedicarboxylic Acid: Synthesis and Structures

Novel vic-dioximes: synthesis, structure characterization, and antimicrobial activity evaluation

“…The recent literature review in CSD [ 51 ] revealed that only two polymorphs of dianylineglyoxime salts as uncoordinated dioxime with “aromatic wings” are known [ 17 ]. We reported new di-aminobenzoylglioxime compounds 1 and 2 with substituents –COOH and –CH 3 in para -positions crystallized in centrosymmetric C 2/ c ( 1 ) and uncentered Pn ( 2 ) monoclinic space groups ( Table S1 ).…”

“…The most common is the N - N -chelation coordination mode favored by the anti-( E , E ) form [ 6 , 13 , 14 ], but the coordination of these ligands via oxygen atoms from oximic groups is also known [ 15 , 16 ]. vic-Dioximes can form coordination compounds in molecular [ 17 , 18 ], monodeprotonated [ 19 – 22 ] and bis-deprotonated [ 23 ] forms. In the coordinated state the intramolecular hydrogen bonds between the oxime anions can be replaced with boron compounds (BF 2 + , BF 2+ , B(C 6 H 5 ) 2 + , B(OH) 2 + ), thus, encapsulating the respective compounds [ 24 – 27 ].…”

“…The condensation reaction of amines or thiols with dichloroglyoxime leads to the formation of different di-, tetra-, poliamino-derivatives or substituted thioglyoximes [ 17 , 36 ]. Through such kind of reactions, a series of new dioximes have been synthesized [ 17 , 37 – 39 ].…”

“…The condensation reaction of amines or thiols with dichloroglyoxime leads to the formation of different di-, tetra-, poliamino-derivatives or substituted thioglyoximes [ 17 , 36 ]. Through such kind of reactions, a series of new dioximes have been synthesized [ 17 , 37 – 39 ]. Both, the oxime and coordination compounds obtained based on their basis show a wide range of pharmacological activities, including antibacterial, antifungal and antidepressant [ 40 – 42 ].…”
