"c NMR spectrum of HZLS with its DEPTl35 spectrum as inset. 2.3.4. Single crystal X-ray diffraction studies The crystal structure data collection of H2L3 was done on a BRUKER SMART APEX CCD diffractometer at Analytical Sciences Division, Central Salt and Marine Chemicals Research Institute, Bhavnagar, Gujarat using graphite monochromated MoKa radiation (l=0.7l073 A) at 273(2) K. A crystal with dimension 0.22 mm>
Chapter 2 0.86 A with Uiso = 1.2 Ucq of the parent atoms, except H(3AN), H(4AN) and H(4BN) which were located from difference maps and were refined isotropically. The data of HZL4 were collected at X-ray Crystallography Unit, School of Physics, Universiti Sains Malaysia, Penang, Malaysia using Bruker SMART APEX2 CCID area detector diffractometer equipped with graphite monochromated Mo K010» = 0.71073 A) radiation at temperature 297(2) K. The trial structure was solved using SHELXS-97 and refinement was carried out by full-matrix least squares on F2 (SHELXTL-97). H atoms attached to N atoms were located in a difference map and refined isotropically. C-bound H atoms were placed in calculated positions and allowed to ride on their parent c atoms, with C—H = 0.93 A and u.,.,(H) = 1.2u,.,(c). The crystallographic data and structure refinement parameters for the compounds HZL3 and HZL4 are given in Table 2.3. The graphics tools used include ORTEP-III [26], PLATON [27], MERCURY [28] and DIAMOND version 3.0 [29]. 2.3.4.1. Crystal structure of HZL3 The compound HZL3, C2,H,6N6S, crystallizes in triclinic form with two independent molecules in the asymmetric unit and exists in the thione tautomeric forms. The two crystallographically independent molecules, A and B are depicted in Fig. 2.16 and their bond lengths and angles are given in Table 2.4, agree with each other and are within normal ranges [30]. Molecule A shows a Z-Z configuration about the C(l0A)—N(2A) and C(12A)—N(5A) double bonds and molecule B shows the same about the C(l0B)—N(2B) and C(l2B)—N(5B) double bonds. A similar configuration was observed in the bisthiocarbohydrazone of 2-benzoylpyridine, HZL2 [1 1], while in 2-acetylpyridine analogue an E-Z configuration exists [9]. The thione S(l) atom is positioned trans to azomethine atom N(2) [The S(l)—C(l l)—N(3)—N(2) torsion angle of -l74.72(2)° for molecule A and l77.67(2)° for molecule B] and cis to azomethine atom N(5) [The S(l)—C(l1)—N(4)—N(5) torsion angle of 4.26(3)° for molecule A and 1.43(3)° for molecule B] in both molecules. 58
