Ferrocenyl-cymantrenyl hetero-bimetallic chalcones: Synthesis, structure and biological properties
(Elsevier, 2015) Sasmita Mishra; Vijaylakshmi Tirkey; Avishek Ghosh; Hirak R. Dash; Surajit Das; Madhulata Shukla; Satyen Saha; Sheikh M. Mobin; Saurav Chatterjee
Two new ferrocenyl-cymantrenyl bimetallic chalcones, [(CO)3Mn(η5-C5H4)C(O)CHCH(η5-C5H4)Fe(η5-C5H5)] (1) and [{(CO)3Mn(η5-C5H4)C(O)CHCH(η5-C5H4)}2Fe] (2) have been synthesized. Their reactivity study with triphenylphosphine and bis-(diphenylphosphino)ferrocene led to the isolation of phosphine substituted bimetallic chalcones (3-6). Single crystal X-ray structural characterization for 1 and its phosphine analogue (3) reveals their different conformational identity with anti-conformation for 1, while syn-conformation for 3. Investigation of antimalarial and antibacterial activities was carried out for compounds 1 and 2 against two strains of Plasmodium falciparum (3D7, K1) and four bacterial strains. TD-DFT calculation was performed for compound 1 and electrochemical properties were studied for bimetallic chalcone compounds by cyclic voltammetric technique. © 2015 Elsevier B.V.

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.
