The title complex, [Cu(C14H14N2O2)2]BF4, is a monomeric copper(I) species with linear two-coordinate geometry around the CuI atom. The contains two half-cations that sit on crystallographic twofold rotation axes. The selected crystal was non-merohedrally twinned by a twofold rotation about an axis normal to the (100) family of planes. The ratio of the twin components refined to 0.4123 (6). Two 2-hydroxy-N-[2-(2-pyridyl)ethyl]benzamide ligands coordinate to each CuI atom via the pyridyl N atom. Intramolecular hydrogen bonding between the phenol OH groups and the amide O atoms imparts rigidity and planarity to the non-coordinating end of the ligand. The cationic complex is linked to the BF4− anions via hydrogen bonding between the amide NH groups in the cations and BF4− anions.

2-hydroxy-N-(2-(2-pyridyl)ethyl)benzamide was synthesized using a previously reported procedure (Wang, et al. 2009). The title complex, [Cu(C14H14N2O2)2]BF4, was synthesized using the following procedure: A solution of [Cu(CH3CN)4]BF4 (0.0778 g, 0.250 mmol) in CH3CN was added to a solution of 2-hydroxy-N-(2-(2-pyridyl)ethyl)benzamide (0.121 g, 0.500 mmol) in CH3CN. The resulting light yellow solution was filtered, and vapor diffusion of diethyl ether produced light yellow crystals of the title complex (0.114 g, 72% yield).
Hydrogen atoms bonded to C were geometrically positioned and refined by a riding model. Hydrogen atom displacement parameters were set to 1.2 (1.5 for methyl) times the displacement parameters of the bonded atoms. The coordinates of the H atoms bonded to N and O were refined with U(H)=1.2Ueq(N,O). The
was (1 0 0.928/ 0 -1 0/ 0 0 -1). The contribution of the minor twin domain refined to 0.437 (4).Our laboratory has synthesized copper(I) and copper(II) complexes of pyridylmethylamide ligands that display different coordination modes depending on whether or not the amide group is protonated (Wang, et al. 2009, and references therein). The synthesis of copper(I) complexes with these ligands is limited to the neutral form of the ligand, where the amide group is not deprotonated (Yang, et al. 2007, and references therein). Attempts to synthesize copper(I) species in the presence of base results in
of the copper(I) to copper(0) and copper(II). The title complex was synthesized with the phenol-substituted ligand 2-hydroxy-N-(2-(2-pyridyl)ethyl)benzamide. Copper(II) complexes with 2-hydroxy-N-(2-(2-pyridyl)ethyl)benzamide are either mononuclear, when synthesized in the absence of base ([Cu(C14H14N2O2)2Cl2]), or a tetracopper cluster, in the presence of base ([Cu4(C14H12N2O2)4]) (Wang, et al. 2009). The ligand in the tetracopper cluster is a dianion with the amide NH and the phenol OH both deprotonated. The title complex differs from both copper(II) complexes in that the ligand only coordinates via the pyridyl N atom.For the synthesis and coordination chemistry of 2-hydroxy-N-(2-(2-pyridyl)ethyl)benzamide, see: Wang et al.

Experimental. The selected crystal was twinned by a 2-fold rotation about an axis perpendicular to c. The ratio of the twin components was refined to 0.4123 (6). |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Restraints on the N—H and O—H distances were required. |

Our laboratory has synthesized copper(I) and copper(II) complexes of pyridylmethylamide ligands that display different coordination modes depending on whether or not the amide group is protonated (Wang, et al. 2009, and references therein). The synthesis of copper(I) complexes with these ligands is limited to the neutral form of the ligand, where the amide group is not deprotonated (Yang, et al. 2007, and references therein). Attempts to synthesize copper(I) species in the presence of base results in disproportionation of the copper(I) to copper(0) and copper(II). The title complex was synthesized with the phenol-substituted ligand 2-hydroxy-N-(2-(2-pyridyl)ethyl)benzamide. Copper(II) complexes with 2-hydroxy-N-(2-(2-pyridyl)ethyl)benzamide are either mononuclear, when synthesized in the absence of base ([Cu(C14H14N2O2)2Cl2]), or a tetracopper cluster, in the presence of base ([Cu4(C14H12N2O2)4]) (Wang, et al. 2009). The ligand in the tetracopper cluster is a dianion with the amide NH and the phenol OH both deprotonated. The title complex differs from both copper(II) complexes in that the ligand only coordinates via the pyridyl N atom.
