title: Bis{2-hydr-oxy-N-[2-(2-pyrid-yl)eth-yl]benzamide}copper(I) tetra-fluoridoborate.
abstract: The title complex, [Cu(C(14)H(14)N(2)O(2))(2)]BF(4), is a monomeric copper(I) species with linear two-coordinate geometry around the Cu(I) atom. The asymmetric unit 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-hydr-oxy-N-[2-(2-pyrid-yl)eth-yl]benzamide ligands coordinate to each Cu(I) atom via the pyridyl N atom. Intra-molecular 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 BF(4) (-) anions via hydrogen bonding between the amide NH groups in the cations and BF(4) (-) anions.
