Copper(ii) complex, 1, of the bidentate ligand, L [L = bis(2-ethyl-4- methyl-imidazol-5yl)methane] has been synthesized and structurally characterized. Addition of nitric oxide gas to a degassed acetonitrile solution of 1 yielded the corresponding copper(ii)-nitrosyl complex, 2. In acetonitrile, complex 2 on reaction with water afforded the corresponding copper(i)-nitrite complex, 3. Single crystal structure of complex 3 reveals the bidentate nitrite (η2-O,O) bonding. This is the first example of a structurally characterized Cu(i)-(η2-O,O)nitrite complex with N-donor ligand. The sequence of the formation of these complexes is just the reverse of the key steps of the postulated nitrite reduction cycle by CuNiRs. The Royal Society of Chemistry 2012.
Complexation of different metals with a novel N-donor bridging receptor and Hirshfeld surfaces analysis

A novel N-donor bridging receptor R: 4,4′-methanediylbis(2-ethyl-5- methyl-1H-imidazole) has been synthesized from 2-ethyl-4-methyl-1H-imidazole and formaldehyde in the presence of potassium hydroxide. This receptor then formed complexes with different transition metals ([Co(NO3)2, CoCl2, Ni(NO3)2 and CuCl2]) in different solvent systems and obtained five different complexes. Wherein, the complex formation of R with Co(NO3)2 resulted in two different structures in methanol and acetonitrile, respectively. A thorough structural investigation of the present receptor and the resulted five complexes show that the NH group of the receptor, the organic anions and solvent molecules play a key role in the construction of the five intriguing architectures. We also prepared molecular Hirshfeld surface and fingerprint plot for R as well as the five complexes, which revealed the influences of different metals to the coordinate behavior of R in terms of intermolecular interactions.
Reductive nitrosylation of nickel(II) complex by nitric oxide followed by nitrous oxide release

Ni(ii) complex of ligand L (L = bis(2-ethyl-4-methylimidazol-5-yl)methane) in methanol solution reacts with an equivalent amount of NO resulting in a corresponding Ni(i) complex. Adding further NO equivalent affords a Ni(i)-nitrosyl intermediate with the
Reaction of a copper(ii)-nitrosyl complex with hydrogen peroxide: Putative formation of a copper(i)-peroxynitrite intermediate

supporting information; experimental part, p. 4636 - 4638 (2012/06/15)
The reaction of a Cu(ii)-nitrosyl complex (1) with hydrogen peroxide at -20°C in acetonitrile results in the formation of the corresponding Cu(i)-peroxynitrite intermediate. The reduction of the Cu(ii) center was monitored by UV-visible spectroscopic stud
