“…[21,22,25,26] In the literature, glycine (Gly; Figure 1B) has coordinated the carboxylate oxygen atom and the amino nitrogen atom in several metalÀ ligand complexes as a bidentate ligand. [21,[25][26][27] The aims of this research were to study the effect of changing atomic volume, and atomic mass of Zn(II) and Sn(II) metal ions with Cl À as counter ion on the biological activities of MOX in the presence of Gly and to examine the mode of coordination and the biological properties of the resultant complexes.…”
