Figure 1
The molecular structure of (II), showing the atom-numbering scheme. The reference asymmetric unit is shown as shaded ellipsoids and filled bonds, while boundary ellipsoids and open bonds represent the symmetry-related half of the tetracopper(II) complex cation. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. Dotted lines indicate hydrogen bonds. [Symmetry code: (i) −x, −y + 1, −z + 1.] |
