摘要

A novel (salicylaldiminato)Pt(II) complex with two different molecular structures, one solventless ((salicylaldiminato)Pt(II)) 1 and another one solvated ((salicylaldiminato)Pt(II)center dot C2H5OH), 1 center dot C2H5OH, has been obtained by the reaction of a salen ligand with [PtCl2(DMSO)(2)] in ethanol at room temperature. The asymmetric unit of solventless 1 contains 9 such complex molecules whereas 1 center dot C2H5OH contains 2 complex molecules and one ethanol molecule. To get insights into the structure and bonding, DFT and TDFT calculation have been carried out. The electronic transition band at 408.0 nm (calc. 424.3 nm) is assigned to HOMO -> LUMO (96%) excitation. The calculated NMR chemical shifts are interrelated with the experimental results, and a very slight effect of solvent was noticed on NMR chemical shifts. A MIT assay and the real-time cell monitoring xCELLigence system revealed that the 1 has significant potential to suppress cell viability and cell proliferation in human HT-29 and SW620 colorectal cancer cell lines.
