Synthesis, structural, chemical properties, and antibacterial screening of Sm(III) thiosemicarbazone complexes

Rare earth complexes can exhibit higher coordination numbers while rare earth metals have the ability to form a multitude of geometries with organic ligands. The ligands, [Sm(III) (4Acpy4MTSC)2 (4H2O)Cl]Cl2 and [Sm(III) (4Acpy4ETSC)(5H2O)Cl2 ]Cl [4Acpy4MTSC = 4-acetylpyridine 4-methyl-3-thiosemicarbazon
