6.3.3.1. Crystal structure 0f[Zn(HL5)]4(BF4)4- IOHZO (29)<br />

The molecular structure <strong>of</strong> 29 with relevant atom numbering scheme is<br />

depicted in Fig. 6.24. Here, the ligand HQLS, in the deprotonated enol tautomer,<br />

adopted a syn configuration to form the complex 29 and is essential for getting<br />

molecular square architectures <strong>of</strong> octahedral centers. Relevant bond lengths and bond<br />

angles <strong>of</strong> 29 are given in Tables 6.4 and 6.5.<br />

Fig. 6.24. ORTEP diagram for the compound 29 in 70% probability ellipsoids.<br />

Phenyl groups, carbon bound hydrogen atoms, anions and water molecules are<br />

omitted for clarity. The hydrogen atoms on N(4), N(1O), N(l6) and N(22) <strong>of</strong> ligand<br />

I-IZLS are retained in the complex, while their counterparts deprotonated on<br />

coordination after enolization.<br />
