These newly synthesized derivatives have been characterized by different physicochemical (elemental analysis (C, H, S, Sb), melting point, molecular weight determination), spectral (UV, IR, NMR (1H, 13C and 31P)) studies, as well as ESI mass, thermal, powder XRD and biological studies. In the final step of weight loss in thermogravimetric analysis, occurring in the range of 245–505 °C, the degradation of the C6H3CO moieties takes place and antimony sulfide (1/2 Sb2S3) is obtained as remaining material, which is useful in various aspects. Bonded to antimony the diisobutyldithiophosphato substituent behaves as an anisobidentate ligand, which is confirmed through spectral analysis. Powder XRD studies indicate that these compounds crystallize in a monoclinic crystal system with an unit cell volume of ∼7074–7162 Å3 forming nano ranged (9.69–15.69 nm) crystallites. From the antimicrobial screening tests, bis(diisobutyldithiophosphato)antimony(III) thioglycolate (compound 3) has shown a maximum zone of inhibition (19 mm) against E. coli at 200 μg mL−1 concentration.

The cross-coupling of 2,4-diaminothiophenol with 2,3-dichloro-1,4-naphthoquin one at room temperature gave reddish brown 10-amino-6-chlorobenzo[a]phenoxazin-5-one which was converted into a benzoxazinophenothiazin-12-amine in 58% yield via reaction with 2-aminothiophenol under anhydrous basic conditions. A three-component one-pot synthesis improved the yield of benzoxazinophenothia-12-amine to 81% a in shorter time compared to two steps reactions.

The products were structurally characterised by IR, 1H NMR, 13C NMR, 19F NMR and HRMS. Anti-bacterial testing showed that most of the evaluated compounds (6a-6s) exhibited excellent activity (≥74.19%) against Xoo at a concentration of 200 µg/mL, with 50% effective concentration (EC50) values ranging from 12.21 to 67.20 µg/mL, which were superior to the commercial antibacterial agent bismerthiazol (92.23 µg/mL).
