Crystal structure of (2,2'-dipyridyl)-(2-hydroxynaphthaldehydato)copper(II) perchlorate.
variability, a great number of Schiff base complexes of copper have been subjected to extensive studies. In comparison with organic molecules, metal complexes offer a wider variety of structures, with comparable or, in some cases, higher environmental stability and a much greater diversity of tunable electronic properties, as a result of the coordinated metal center.1 We report here the results...
متن کاملCrystal structure of 2-cyano-1-methylpyridinium perchlorate
The asymmetric unit of the title salt, C7H7N2 (+)·ClO4 (-), comprises two independent formula units. The solid-state structure comprises corrugated layers of cations and of anions, approximately parallel to (010). The supra-molecular layers are stabilized and connected by C-H⋯O hydrogen bonding to consolidate a three-dimensional architecture. A close pyridin-ium-perchlorate N⋯O contact [2.867 (...
متن کاملCrystal Structure of Schiff base Compound 2-[(2-chloro-4-nitrophenyl) iminomethyl] phenol
Single crystals of Schiff base compound 2-[(2-chloro-4-nitrophenyl) iminomethyl] phenol (1) were grown by the slow evaporation technique at room temperature. The crystal structure of the title compound was determined by single crystal X-ray diffraction. The title compound crystallizes in the monoclinic system, space group P21, with two symmetry independent molecules. Intramolecular O-H···N hydr...
متن کاملCrystal Structure and Nanoparticles of Dinuclear Silver(I) Complex [Ag2(PPh3)2(μ-S-4nb-tsc)2(η1-S-4nb-tsc)2](NO3)2
Nanoparticles of a new dinuclear silver(I) complex [Ag2(PPh3)2(μ-S-4nb-tsc)2(η1-S-4nb-tsc)2](NO3)2, where 4nb-tsc = 4-nitrobenzylidenethiosemicarbazone and PPh3 = triphenylphosphine, were prepared in an ultrasonic bath and characterized by FT-IR and SEM. The crystal structure of a suitable single crystal prepared by slow evaporation was determined by single crystal X-ray diffraction. The compou...
متن کاملThe unexpected role of pyridine-2-carboxylic acid in manganese based oxidation catalysis with pyridin-2-yl based ligands.
A number of manganese-based catalysts employing ligands whose structures incorporate pyridyl groups have been reported previously to achieve both high turnover numbers and selectivity in the oxidation of alkenes and alcohols, using H(2)O(2) as terminal oxidant. Here we report our recent finding that these ligands decompose in situ to pyridine-2-carboxylic acid and its derivatives, in the presen...
