[Cu(phdpa)Cl]+ (phdpa=bis(2-pyridylmethyl)aniline): A moiety of unusual stability in some 1:1 Cu(II) complexes of phdpa. Synthesis and X-ray crystal structures of [Cu(phdpa)Cl2] and [Cu2(phdpa)2Cl3]PF6 ·0.5MeOH

1:1 copper(II) complexes of bis(dipyridylmethyl)aniline (phdpa) of various kinds, with chloride and PF6- as anions, were synthesized and characterized by elemental analysis, IR spectroscopy and X-ray structure crystallography. The crystal structures of [Cu(phdpa)Cl2] (I) and [Cu2(phdpa)2Cl3]PF6 ·0.5MeOH (II) showed that the metal atoms are five-coordinated and that the structures are also stabilized by a triple intramolecular hydrogen-bond system. The resulting unusual stability of the [Cu(phdpa)Cl]+ moiety influences the exchange properties with PF6- of compound I, which gave complexes where the cationic group is maintained also under drastic reaction conditions.

Isomerism in copper(II) chloride complexes of bis(2-pyridylmethyl)amine and N-substituted derivatives: Synthesis and X-ray structural characterisation

Copper(II) chloride complexes of tridentate N-alkylated bis(2-pyridylmethyl)amine ligands (R-bpa) form coordination oligomers with either terminal or bridging chloride. Two structural types are identified by X-ray diffraction: a mono μ-chloro bridged species and a di-μ-chloro bridged species, both containing five-coordinate copper(II). In each case, the τ parameter indicates only small deviations from regular square-pyramidal coordination geometry. The product structure is dependent on the presence or absence of non-coordinating anions. In the presence of ClO4- or PF6-, cationic dinuclear complexes are formed, driven by the formation of an ionic lattice. In the absence of non-coordinating anions, neutral mononuclear [CuCl2(R-bpa)] complexes are formed. Chloride concentration in methanol solution exerts less influence on the reaction outcome, despite differing chloride stoichiometries in the isolated products. In the presence of the coordinating acetate anion, cationic products are formed in which the terminal chloride ligands are completely or partially substituted by acetate.

Syntheses, structures, and properties of copper(II) complexes of bis(2-pyridylmethyl) derivatives of o-, m-, and p-phenylenediamine and aniline

Copper(II) complexes of the ligand 1,n-bis[bis(2-pyridylmethyl)amino] benzene with n = 2-4 (1,n-tpbd) and its mononuclear derivative bis(2-pyridylmethyl)aniline (phbpa) were synthesized and structurally characterized. Magnetic measurements and DFT calcula
