TL;DR: In this article, a trinuclear mixed-valence complex of the type [CoII(µ-SO3)2( µ-L)2CoIII2(H2O)n(ROH)2−n]·2PrnOH showed the presence of bridging phenolic oxygens and sulphite ions.
Journal ArticleDOI
Synthesis and characterization of trinuclear Schiff-base complexes containing sulphur dioxide or hydrogensulphite ions as bridging groups. Crystal structure of [Zn{(µ-CH3CO2)(salpd-µ-O,O′)Cu}2][salpd = propane-1,3-diylbis(salicylideneiminate)]
Chōki Fukuhara,Kazuhiko Tsuneyoshi,Naohide Matsumoto,Sigeo Kida,Masahiro Mikuriya,Masayasu Mori +5 more
TL;DR: In this article, a trinuclear complex of general formulas [MCu2(CH3CO2SO2)2(salpd)2] was prepared, where H2salpd represents propene-1,3-diylbis(salicylideneimine).
Journal ArticleDOI
Linear tetranuclear copper(II) complexes with bridging methoxide and a schiff-base ligand : the preparation and magnetic study of the [Cu(salpd-μ-O,O')(μ-L)Cu(μ-CH3O)2Cu(μ-L)(sapd-μ-O,O')Cu] complexes (and L=acetate or formate ions) and the structure determination of the complex with L=acetate
TL;DR: In this paper, the title complexes have been synthesized in quantitative yield from [Cu(salpd)] and copper(2) acetate or copper(II) formate, where H2salpd represents N,N′-disalicylidene-1,3-propanediamine.
Journal ArticleDOI
Mixed-ligand schiff base cobalt(III) complexes with phenolaldehydes or phenolketones as ligands
Chōki Fukuhara,Satoru Matsuda,Kosho Katsura,Masayasu Mori,Keiji Matsumoto,Shun'ichiro Ooi,Yuzo Yoshikawa +6 more
TL;DR: In this paper, mixed-ligand cobalt(III) complexes of the type [Co(L)(SB)] were prepared and characterized, where L is an aldehyde- or ketone-phenolate anion such as salicylaldehydate (sal), 5-chlorosalicyldehyddate (5-Cl-sal), 3,5-dichlorsalicyl de-de-hyde (3,5)-sal, or o-hydroxyacetophenonate (oap), whereas SB is a deprotonated Schiff base
Journal ArticleDOI
Studies on cobalt(III) complexes with (R,S)-8-amino-2-methyl-3,6-diazaoctanoate ion. II. Determination of absolute configuration of mixed complexes with the (S)-alaninate ligand
TL;DR: In this paper, five optically active diastereoisomers chromatography results were obtained for the trans-O and β-mer (N) cis (O) cobalt(III) complexes with (R,S )-8-amino-2-methyl-3,6-diaza octanoate ion (S -ala) and their absolute configurations were assigned in the order of elution to Δ S R (3 S,6 R ), Λ S S (3 R,6 S ), Δ S S(3 S,6 S
