چکیده
The asymmetric redox-active ligand 4,5-bis(pyridine-2-carboxamido)-1,2-catechol ((N,O)LH4) is prepared and metalated to afford the hexanuclear complex [Mn6((N,O)L)6](6-). Structural analysis and magnetic measurements reveal this complex to feature Mn(II) ions bridged by (N,O)L(3-)˙ radicals, which are antiferromagnetically coupled to give an S = 12 ground state.

A series of tetraazalene radical-bridged M2 (M = CrIII, MnII, FeII, CoII) complexes with strong magnetic exchange coupling.
The ability of tetraazalene radical bridging ligands to mediate exceptionally strong magnetic exchange coupling across a range of transition metal complexes is demonstrated. The redox-active bridging ligand N,N',N'',N'''-tetra(2-methylphenyl)-2,5-diamino-1,4-diiminobenzoquinone (NMePhLH2) was metalated to give the series of dinuclear complexes [(TPyA)2M2(NMePhL2-)]2+ (TPyA = tris(2-pyridylmethy...
متن کاملRedox-Active Metal-Organic Nanostructure Polymers and Their Remarkable Electrochemical Behavior
A number of redox-active coordination polymers (CPs) or metal- organic frameworks (MOFs) have been successfully synthesized using transition metals and bridging ligands. This article aims to deal with gathering the aforementioned disperse issues regarding the electroactive CPs. It also goes towards illustrating the effects of various factors on the electrochemical behavior of CPs including...
متن کاملN-heterocyclic phosphenium and phosphido nickel complexes supported by a pincer ligand framework.
A chelating diphosphine ligand with a central N-heterocyclic phosphenium cation (NHP(+)) has been used to explore the coordination chemistry of NHPs with nickel. Treatment of the chlorophosphine precursor [PPP]Cl (1) with stoichiometric Ni(COD)2 affords (PPP)NiCl (8), which is best described as a Ni(II)/NHP(-) phosphido complex formed via oxidative addition of the P-Cl bond. In contrast, treati...
متن کاملBiomimetic model for [FeFe]-hydrogenase: asymmetrically disubstituted diiron complex with a redox-active 2,2'-bipyridyl ligand.
[FeFe]-hydrogenases feature a unique active site in which the primary catalytic unit is directly coordinated via a bridging cysteine thiolate to a secondary, redox active [4Fe4S] unit. The goal of this study was to evaluate the impact of a bidentate, redox non-innocent ligand on the electrocatalytic properties of the (μ-S(CH(2))(3)S)Fe(2)(CO)(4)L(2) family of [FeFe]-hydrogenase models as a prox...
متن کاملSpin exchange effects on the physicochemical properties of tetraoxolene-bridged bimetallic complexes.
The synthesis, physical, and spectroscopic properties of a series of metal complexes bridged by the redox-active chloranilate ligand are described. Compounds containing the (CAcat,cat)4- ligand, where (CAcat,cat)4- represents the fully reduced aromatic form of chloranilate, have been prepared by two different routes from H2CA and H4CA starting materials; the corresponding (CAsq,cat)3- analogue ...
