Journal ArticleDOI
An approach to the O2 activating mononuclear non-heme Fe enzymes: structural characterization of Fe(II)–acetato complex and formation of alkylperoxoiron(III) species with the highly hindered hydrotris(3-tert-butyl-5-isopropyl-1-pyrazolyl)borate
Tamako Ogihara,Shiro Hikichi,Munetaka Akita,Takeshi Uchida,Teizo Kitagawa,Yoshihiko Moro-oka +5 more
TL;DR: In this paper, the structural characterization of an Fe(II)-acetato complex and attempts to synthesize mononuclear Fe(III) dioxygen complexes bearing the highly sterically demanding TptBu,iPr ligand have been investigated.
Journal ArticleDOI
Selective Synthesis, Characterization, and Configurational Flexibility of the Coordinatively Unsaturated Metal Center of Half-Sandwich Type Complexes with the Less-Hindered Hydrotris(3, 5-dimethyl-4-X-1-pyrazolyl)borate Ligands [TpMe2,XMII(κ2-O,O′-L)] (M = Ni, Co; L = NO3, OAc; X = Me, H, Br)
Shiro Hikichi,Yasuyuki Sasakura,Michito Yoshizawa,Yoshiko Ohzu,Yoshihiko Moro-oka,Munetaka Akita +5 more
TL;DR: In this article, the half-sandwich type complexes of Ni (II) and Co(II) with the less-hindered hydrotris(3,5-dimethyl-4-X-1-pyrazolyl)borate ligands were synthesized by dropwise addition of a THF solution of NaTpMe2,X to an excess amount of ML2 dissolved in MeOH.
Journal ArticleDOI
Novel monoanionic tripodal ligands: methylbis(1-methylimidazol-2-yl)(pyrazol-1-yl)borate (= [MeB(ImN-Me)2(PzR)]−). Synthesis and structural characterization of their nickel complexes and carboxylate shift from nickel to boron
TL;DR: In this article, a novel monoanionic tripodal ligands, [MeB(ImN-Me)2(PzR)]− (= methylbis(1-methylimidazol-2-yl)(pyrazol-1-yl)borate), are synthesized; their mode of coordination to a nickel center depends on the steric congestion around the boron centers.
Journal ArticleDOI
An entry to half-sandwich complexes of first row transition metals (Ni, Co, Mn) containing the Kläui tripodal ligand, LOMe: synthesis and crystal structures of oligomeric, [LOMeM(μ-X)(L)]n (n = 2, 4), and monomeric complexes, LOMeM(L2)(X)
TL;DR: A series of half-sandwich complexes of Ni, Co and Mn containing the Klaui tripodal ligand LOMe [κ3-(η5-C5H5)Co{P(O)(OCH3)2}3] are prepared by reaction of the labile precursors as mentioned in this paper.
Journal ArticleDOI
Xenophilic Complexes Bearing a TpR Ligand, [TpRM ? M′Ln] [TpR=Tp, Tp# (Tp); M=Ni, Co, Fe, Mn; M′Ln=Co(CO)4, Co(CO)3(PPh3), RuCp(CO)2]: The Two Metal Centers are Held Together not by Covalent Interaction but by Electrostatic Attraction
TL;DR: Unrestricted DFT calculations for the model complexes prove that the two metal centers are held together not by covalent interactions, but by electrostatic attractions, and the obtained xenophilic complexes can be regarded as carbonylmetalates.
