Synthesis of mono- and bi-metallic dithiocarboxylate-alkyne complexes from sunlight driven insertion reaction and their antibacterial activity

Abstract

Sunlight driven synthesis, characterization and antibacterial evaluation of cyclopentadienyl based metal-dithiocarboxylate alkyne complexes, [LM(CO) n(η2-S2C)CCR], [{L = η5- C5H5, M = W, R = (η5-C5H 4)Fe(η5-C5H5), n = 2}; {L = η5-C5H5, M = W, R = -C(CH 3)CH2, n = 2}; {L = η5-C5H 5, M = Mo, R = -C(CH3)CH2, n = 2}; {L = η5-C5Me5, M = Fe, R = Ph, n = 1}] (5-8) have been carried out. Reactivity of metal-dithiocarboxylate alkyne complexes towards dicobaltoctacarbonyl were studied to obtain a trimetallic dithiocarboxylate complex (9-11). Structural characterizations of 7 and 8 have been carried out crystallographically and DFT calculation was performed on compound 8 to understand the electronic properties of the complex. © 2013 Elsevier B.V.
