A new chiral [Ni15] complex with a Schiff-base ligand derived from o-vanillin and L-glutamic acid is presented, emphasizing the properties relevant for biology and materials science. The formation of the complex molecules in solution is confirmed by AFM and dynamic light scattering studies. The compound is weakly antiferromagnetic with considerable admixture of excited states, comprising negligibly interacting [Ni3] units. Studies of the interactions with two cell lines indicate low cytotoxicity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
