The tripodal ligand N[CH2CH2NHC(O)NHC(CH3)3]3 ([H6 1]) was used to synthesize a series of monomeric complexes with terminal hydroxo ligands. The complexes [CoII/IIIH3 1(OH)]2-/1-, [FeII/IIIH3 1(OH)]2-/1- , and [ZnIIH3 1(OH)]2- have been isolated and

A neutral 1-D supramolecular array containing [Mn(H2)2] building blocks was synthesized by the selective deprotonation of two coordinated imidazole moieties from the cationic Mn(II) complex, [Mn(H22)2]2+. Upon deprotonation the redox potential of [Mn

Four new Mo(VI)-dioxo complexes of a family of N2X heteroscorpionate ligands are reported which, together with data already available for (TpR)-, provide a unique example of a comprehensive set of isostructural, isoelectronic complexes differing only

We have previously demonstrated that the complex [(L1O)MoOCl(2)], where L1OH = (2-hydroxy-3-tert-butyl-5-methylphenyl)bis(3,5-dimethylpyrazolyl)methane, exists as both cis and trans isomers (Kail, B.; Nemykin, V. N.; Davie, S. R.; Carrano, C. J.; Ham

The syntheses and characterization of a series of zinc complexes containing the tripodal ligand bis(5-tert-butyl-3-methylpyrazol-2-yl)acetic acid (H2) which is designed to model the 2-His-1-carboxylate facial triad observed in the active sites of var

Reaction of the Zn, Cd, or Co nitrate salts with the deprotonated ligand (2-hydroxy-3-t-butyl-methylphenyl)bis(3,5-dimethylpyrazolyl)methane (L1O−) in methanol produced the following complexes: [(L1OH)Zn(NO3)2] in two isomorphs, a = 40.983(8) A, b

As models for the labile water ligands so ubiquitous in zinc metalloprotein active sites, aquo and hydroxo complexes of zinc with the ester substituted trispyrazolylborate ligand, [(TpCO2Et,Me) have been isolated and crystallographically characterize

The hydrogen-bond accepting ligand K[TpCO2Et,Me] was prepared and its complexes with divalent Ni, Co, Mn and Cu reveal a stabilization of penta- or hexa-coordinate metal aquo complexes of the general form [TpCO2Et,MeM(H2O)x] (x = 2 or 3) which are un

The Zn(II)CH3 complexes of the heteroscorpionate ligands (3-tert-butyl-2-hydroxy(or thio)-5-methylphenyl)bis(3,5-dimethylpyrazolyl)methane, L1OH or L2SH react with pentafluorothiophenol (HSPhF5). For [(L1O)ZnCH3], this resulted in the formation of
