Figure 2
A stereoview, approximately down the a axis, of the crystal structure of (I), illustrating the coordination polymerization scheme. Each porphyrin unit is coordinated to four neighbouring species via two Zn—O(=C) and two (C=)O—Zn bonds of 2.540 (2) Å. The Zn, N and O atoms are indicated by darkened spheres, and the C atoms by open circles. H atoms have been omitted for clarity. |
