, and [(NiL) 4 (V 10 O 29 )] n (5), have been obtained by the reaction of the macrocyclic nickel complex [NiL](ClO 4 ) 2 (L = 1,4,8,11-tetraazacyclotetradecane) with NH 4 VO 3 under different conditions. Single-crystal X-ray diffraction analyses revealed that the [VO 3 ]anion assumes diverse species and structures in these five coor- [a]
Two dinuclear succinato-bridged nickel(II) complexes [Ni(RR-L)] 2 (μ-SA)(ClO 4 ) 2 (1) and [Ni(SS-L)] 2 (μ-SA)(ClO 4 ) 2 (2) (L = 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane, SA = succinic acid) were synthesized and characterized by EA, Circular dichroism (CD), as well as IR and UV/Vis spectroscopy. Single crystal X-ray diffraction analyses revealed that the Ni II atoms display a distorted octahedral coordination arrangement, and the succinato ligand * Dr. G. C. Ou
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.
