A chirally helical coordination polymer,5-dicarboxylic acid) constructed from a Ni 4 L 4 building block exhibits spontaneous chiral resolution and the enantiomers of 1M and 1P have been confirmed by singlecrystal analysis and solid-state circular dichroism spectra. The magnetic properties of compound 1 are also discussed.
An enantioenriched three-dimensional quartz-type framework {[Ni(1.5)(tzdc)(H(2)O)(3)]·3H(2)O}(n) (H(3)tzdc = 4H-1,2,4-triazole-3,5-dicarboxylic acid) possessing chiral channels is obtained through spontaneous asymmetric crystallization without any enantiopure additive.
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.
