“…The pyim ligand as a whole does not deviate significantly from the planarity, the dihedral angle between the imidazole and pyridyl rings being 1.0(3)°. The value of the inter-ring C(12)−C(13) bond length [1.444(7) Å] as well as the geometric parameters of the imidazole and pyridyl fragments of the pyim ligand agree with those reported for this group in the complexes [Cu(pyim)(C 2 O 4 )(H 2 O)]·2H 2 O (C 2 O 4 2− = dianion of oxalic acid), [Cu(pyim)(C 4 O 4 )(H 2 O) 2 ]·2H 2 O (C 4 O 4 2− = dianion of squaric acid), [Cu(pyim)(H 2 O)(dca)] n (dca = dicyanamide anion), and [Cu(pyim) 2 Br]ClO 4 …”

Six new copper(II)-malonate containing complexes [Cu(dpydiol)(mal)(H2O)]·2H2O (1) (dpydiol = bis(2-pyridyl)methanediol), [Cu(dpa)(mal)(H2O)]·H2O (2) (dpa = 2,2′-dipyridylamine), [Cu(pyim)(mal)(H2O)]·H2O (3) (pyim = 2-(2-pyridyl)imidazole), [Cu(dpp)(mal)(H2O)]·3/2H2O (4) (dpp = 2,3-bis(2-pyridyl)pyrazine), [Cu(phen)(mal) (H2O)]·H2O (5), and [Cu2(phen)2(mal)(H2O)3](NO3)2·2H2O (6) (phen = 1,10-phenanthroline) were prepared and their structures were determined by single-crystal X-ray diffraction analysis. 1−5 are mononuclear complexes, whereas 6 is a dinuclear species. The neutral mono- and dinuclear units and the crystallization water molecules are linked together by hydrogen bonds to afford three-dimensional networks. In addition, π···π stacking (2, 5 and 6) and hydrophobic (4 and 6) interactions contribute to the stabilization of the structures. The analysis of the magnetic data of 6 in the temperature range 1.9–300 K shows the occurrence of a significant ferromagnetic interaction between the copper(II) ions through the carboxylate−malonate bridge [J = +6.22(1) cm−1, the isotropic spin Hamiltonian being defined as Ĥ = −JŜ A·Ŝ B].

Pyrazole‐Based Ligands for the [Copper–TEMPO]‐Mediated Oxidation of Benzyl Alcohol to Benzaldehyde and Structures of the Cu Coordination Compounds

et al. 2007

View full text Add to dashboard Cite

New pyrazole‐based ligands have been designed, and the catalytic performances of their copper(II) complexes for the [copper/TEMPO]‐mediated oxidation of benzyl alcohol to benzaldehyde have been examined. The pyridine‐pyrazole ligands give efficient catalysts, while the use of naphthol‐pyrazole ligands results in inactive catalytic systems. Single‐crystals of four Cu coordination compounds obtained from pyridine‐pyrazole ligands and a free ligand have been isolated and were characterized by X‐ray diffraction. Thus, the solid‐state structures of three copper(II) complexes are described, together with a copper(I) coordination chain, exhibiting luminescent properties. (© Wiley‐VCH Verlag GmbH & Co.
