Figure 2 Octahedral geometry at Zn1A (left) and trigonal bipyramidal geometry at Zn1B (right). In-plane bond angles (°) have been indicated. N3-Zn1-N4 undergoes an opening of 27.4° from B to A to accommodate the extra perchlorate ligand O1D. In both complexes the N5-Zn1-N3/N4/O1 angles are slightly larger than the N2-Zn1-N3/N4/O1 angles, with ranges 96.0 - 102.8° and 78.7 - 80.3°, respectively.  [article HTML]
