TL;DR: It is reasonable to conclude that the replacement of chloride anion by a large organic anion in sertraline strengthens the pharmacological action of the native drug, binding to BSA with higher activity and retaining the antimicrobial activity of the antidepressant compound.

TL;DR: In this article, a new general synthetic procedure for preparation of Na3[Fe(C2O4)3]·5H2O (1), Rb3[ Fe(C 2O4]·3H 2O (2), and Cs3[F2O 4]·2H 2 O (3) was developed.
Abstract: A new general synthetic procedure for preparation of Na3[Fe(C2O4)3]·5H2O (1), Rb3[Fe(C2O4)3]·3H2O (2), and Cs3[Fe(C2O4)3]·2H2O (3) was developed. The crystal structures of these salts have been determined by single crystal X-ray diffraction. Salt 1 crystallizes in the monoclinic space group C2/c with Z = 8, salt 2 in P21/c with Z = 4, and salt 3 in P21/n with Z = 4. The three new salts and K3[Fe(C2O4)3]·3H2O, prepared for comparative purposes, were further characterized by infrared and 57Fe-Mossbauer spectroscopy. These spectra are discussed in comparison with those of related oxalato complexes.
