چکیده

The structure of the title compound, [Cu(ClO4)2(C16H38N6)] has been determined from synchrotron data, λ = 0.62988 Å. The asymmetric unit comprises one half of the Cu(II) complex as the Cu(II) cation lies on an inversion center. It is coordinated by the four secondary N atoms of the macrocyclic ligand and the mutually trans O atoms of the two perchlorate ions in a tetra-gonally distorted octa-hedral geometry. The average equatorial Cu-N bond length is significantly shorter than the average axial Cu-O bond length [2.010 (4) and 2.569 (1) Å, respectively]. Intra-molecular N-H⋯O hydrogen bonds between the macrocyclic ligand and uncoordinating O atoms of the perchlorate ligand stabilize the mol-ecular structure. In the crystal structure, an extensive series of inter-molecular N-H⋯O and C-H⋯O hydrogen bonds generate a three-dimensional network.
