Reactions Between Dinuclear CuII–NiII Complexes and the Nitrito Ligand: A New One-Dimensional Complex [Cu(oxpn)Ni(µ-NO2)(trimen)]n(ClO4)n with Nitrite Acting as a Tridentate Bridging Ligand and Ferro- and Antiferromagnetic Alternation

NaCl-Type Frameworks of [M(pyrazine)2NO2]ClO4 (M = Co, Cu), the First Examples Containing μ1,3-Nitrito Bridges Showing Antiferromagnetism

“…The unique M−N/O bonds are 2.160/2.068 Å ( 1Co ) and 2.049/2.285 Å ( 2Cu ), and all N/O−M−N/O angles are ideal 90 or 180°. The O−N−O angle of NO 2 - , in the structures, is 180°, not bent as documented. − However, the flat, disklike thermal ellipse of N/O atoms (Figure S1a of the Supporting Information) revealed the bent characteristic of NO 2 - . The thermal ellipses have their long axes ( U 11 = U 22 , the principal mean-square atomic displacements) perpendicular, while the short one ( U 33 ) parallel to the M···M line or the 4-fold axis, and the ratio of U 11 / U 33 is ca.…”

Synthesis, crystal structures and spectroscopic properties of two novel oxamido-bridged trinuclear complexes [Cu2M] (M = Cu, Zn)

“…using mononuclear complex which contain potential donor groups towards another metal ion [5][6][7][8][9]. Following these principles, many homonuclear complexes in which the metals have different geometries or oxidation states [10][11][12][13][14] or heteronuclear complexes [15][16][17] and even 1D to 3D supramolecular architectures which were constructed through hydrogen bonds or small inorganic bridge (N 3 ) ) [18,19] have been reported.…”

Oxamide Derivatives as Potent α ‐Glucosidase Inhibitors: Design, Synthesis, In Vitro Inhibitory Screening and In Silico Docking Studies

“…Good to moderate inhibitory activities were observed for all synthetic derivatives against α-glucosidase enzyme. Off twenty (20), nine (9) compounds were found to exhibit good inhibitory activities (IC 50 ranges in between 38.2-75.8 μM) when compared with the standard 1-deoxynojirimycin (DNJ) with IC 50 = 425.6 � 1.3 μM. Molecular docking studies were performed for the evaluation of binding mechanism of oxamide compounds in the pocket of α-glucosidase enzyme.…”

“…[1][2][3][4][5][6][7][8][9] Oxamide, a unique representative of amide, also have gained significant interest due to a variety of their applications in medicine, catalysis, magnetism, anticancer, antiproliferative, and antiinflammatory activities. [10][11][12][13][14][15] Most of the oxamides have also significant biological importance and inhibit several enzymes such as HIV-I protease, aldose reductase, tumor necrosis factor, [16][17][18][19][20][21][22] complement component 5a (C5a), [23] acetylcholinesterase, [24] anti-HIV, [25][26][27] HIV integrase, [28][29][30][31] as well as nitric oxide synthase, [32] and also play an important role in antiepileptic drugs. [33] This is mainly due to the presence of active amide group that is profoundly used in drug synthesis and natural product chemistry.…”
