“…In this study, a new ligand N,N-((1E,2E)-ethane 1,2diylidene)bis(azanylylidene)di(isonicotinohydrazide) and its metal complexes (1-6) were synthesized and characterized. Powdered samples of complexes ( 3) and (6) were exposed to 60 Co γray at two different irradiation doses (150 and 200 kGy) at room temperature to yield complexes (3F and 3F*) and (6F and 6F*), respectively. Molar conductivity, FT-IR, UV-Vis., magnetic moment, TGA, mass spectrum, PXRD patterns, cytotoxic activity of compounds on MCF-7 and Hep-G2 cell lines, and ct-DNA interaction were all performed before and after γ-irradiation; in addition, docking process for the ligand and complexes (3) and ( 6) was evaluated.…”

Bis Schiff base N,N–((1E,2E)‐ethane 1,2diylidene)bis(azanylylidene)di(isonicotinohydrazide) ligand L was reacted with Fe (III), Ni (II), Co (II), and Hg (II) chlorides to yield complexes (1–6). The structure of the synthesized ligand and metal complexes was well established by various spectroscopic techniques (Fourier‐transform infrared [FT‐IR], UV–Vis., and 1H NMR), mass spectrometry, elemental analysis (CHN) and physical studies (thermogravimetric analysis [TGA]/first derivative thermogravimetric analysis [DTG], powder X‐ray diffraction, molar conductance, and magnetic moment). Solid powder samples of the binuclear complexes (3 and 6) were irradiated at two different irradiation doses (150 and 200 kGy) to yield complexes (3F and 3F*) and (6F and 6F*), respectively. For the γ‐irradiated samples, FT‐IR, UV–Vis., and physical studies (TGA/DTG, X‐ray diffraction, molar conductance, and magnetic moment) were performed using the same methods as for the as‐prepared complexes. In addition, calf thymus ct‐DNA binding results monitored by agarose gel electrophoretic method indicated that the as‐prepared binuclear [Hg2LCl4(OH)2] complex (6) and its γ‐irradiated [Hg2LCl4(OH)2] complex (6F) have the ability to cleave ct‐DNA at a concentration of 30 and 70 μg/ml, respectively. Inhibitory activity against hepatocellular carcinoma cells (HepG‐2) and breast carcinoma cells (MCF‐7) of ligand and as‐prepared complexes (3, 6, and 6F) was evaluated. The results revealed that metal complexes exhibited enhanced activity in comparison to the free ligand, and the as‐prepared complex (6) shows an IC50 value of 5.7 ± 0.2 and 8.72 ± 0.6 μg/ml for the two cell lines, respectively. Docking process for the ligand and complexes (3) and (6) with liver cancer protein (ID: 4FM9) and breast cancer protein (ID: 1H7K) has been evaluated.

“…[59] Also, the size of the crystal may change due to the stress caused by irradiation. [29,60] The suggested structures for the complexes based on elemental analyses, molar conductance measurements, magnetic susceptibilities, XRD, and different spectral and thermal data are shown in Figure 4.…”

“…The measured magnetic moment at room temperature is 4.7 BM. The presence of spectral band and magnetic moment are consistent with those expected for tetrahedral coordinate [27,33].Moreover, the electronic absorption spectra of Co(II) complexes (2) and (3) display d-d transition bands at (650, 550) and (550) nm assigned to 4 A2g(F)→ 4 T1(P) , 4 T1g(F)→ 4 A2g(F) and 4 T1g(F)→ 4 A2g(F), respectively, suggesting an octahedral geometry around Co (II) ion for both complexes [6,27,[34][35][36][37][38]. The magnetic moment values of complexes (2,3) are within the reported range of 4.8-5.6 BM ( Table 3).…”

Novel metal complexes of Co(II) and Ni(II) have been prepared from reaction of their different salts with previously prepared ligand (L) namely (N,N'-(1,2-phenylene)bis(2-aminobenzamide). Synthesis ligand and its metal (II) complexes (1-5) were reported and characterized with the help of analytical and physiochemical analysis as elemental, IR spectra, thermal (TG/DTG), UV-Vis, magnetic susceptibility and molar conductance in DMF, On the view of the previous data and measurements, the structure and composition species behave as mononuclear and octahedral geometry has been proposed for all the complexes except for complex (1) adopted tetrahedral structure. Furthermore, the in vitro antibacterial Staphylococcus aureus (ATCC 25923) as Gram-positive strain, Escherichia coli (ATCC 25922) as Gram-negative strain and antifungal Candida albicans (ATCC 10231) have been studied for all samples using disc diffusion method against Ampicillin and Fluconazole as positive controls, respectively. The results show that complexation facilitates the activity of most studied metal complexes than the free ligand.
