【 摘 要 】

The title compound, [Cu(NO3)2(C10H16N2O)], has been synthesized and characterized by synchrotron single-crystal diffraction at 100 K. The CuII ion has a distorted square-pyramidal coordination geometry with two N and one O atoms of the C10H16N2O ligand and one nitrate anion in the equatorial plane and another nitrate anion at the axial position. The equatorial Cu—N and Cu—O bond lengths are in the range 1.9608 (14)–2.0861 (15) Å, which are shorter than the axial Cu—Onitrate bond length [2.1259 (16) Å]. In the crystal, molecules are linked via intermolecular N—H...O and O—H...O hydrogen bonds, forming a sheet structure parallel to the bc plane. The sheets are further linked through a face-to-face π–π interaction [centroid–centroid distance = 3.994 (1) Å]. Weak intermolecular C—H...O interactions are also observed in the sheet and between adjacent sheets.
