“…In (I) ( Fig. 1), the C3-N1 and C-S bond lengths are within the standard ranges for C N (Liu et al, 2002) and C S bonds (Jian et al, 2006). There is a dihedral angle of 57.91 (1) between the plane through atoms S1, N1, N2, N3, C1, C2, C3 and C4 and the benzene ring (C4-C9).…”

“…Schiff bases have been used extensively in the field of coordination chemistry (Jian et al, 2006). They also have antimicrobial (Tarafder et al, 2000) and anticancer applications (Deschamps et al, 2003).…”

“…Schiff bases have been used extensively as ligands in the field of coordination chemistry (Jian et al, 2006). They are potential antimicrobial and anticancer agents (Tarafder et al, 2000;Deschamps et al, 2003) and so have biochemical and pharmacological applications.…”
