Figure 5
Out-of-plane metal coordination by pyridine in one of the two symmetrically independent polymer strands in (4). The site symmetry of the Cd center is 2/m. (a) Displacement ellipsoid plot (90% probability, H atoms omitted); (b) Laplacian of the electron density [±2n × 10−3 e Å−5 (0 ≤ n ≤ 20), negative values solid] in the region of the Cd2—N2 bond; the view direction is in the plane through the pyridine ring and perpendicular to Cd1—N1; (c) Deformation density in the plane of the pyridine ligand (intervals at 0.1 e Å−3, excess density solid). |
