Crystal structure of {2-methyl-2-[(pyridin-2-yl-meth-yl)amino]-propan-1-ol-κ(3) N,N',O}bis-(nitrato-κO)copper(II) from synchrotron data.

The title compound, [Cu(NO(3))(2)(C(10)H(16)N(2)O)], has been synthesized and characterized by synchrotron single-crystal diffraction at 100†K. The Cu(II) ion has a distorted square-pyramidal coordination geometry with two N and one O atoms of the C(10)H(16)N(2)O 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)†à , which are shorter than the axial Cu-O(nitrate) bond length [2.1259†(16)†à ]. In the crystal, mol-ecules are linked via inter-molecular 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 inter-action [centroid-centroid distance = 3.994†(1)†à ]. Weak inter-molecular C-H⋯O inter-actions are also observed in the sheet and between adjacent sheets.
