Aroilbis(N,N-dietiltioureatos) de cádmio (II) e chumbo (II): síntese e caracterização
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2014-07-18)
This work introduces the synthesis of two novel ligands belonging to the aroylbis(thiourea) class to study the spacer group influence in the complexes structure. Five membered rings were utilized as spacer groups such as ...
Stereoselective synthesis of dodecaammine-ì-hexoltetracobalt(III) in carbohydrates solution Sintesis estereoselectiva de dodecamino-μ-hexoltetracobalto(III) en presencia de hidratos de carbono
(2002)
Reaction between cis-[Co(NH3)(H2O)(2)](3-) and ammonia in aqueous solution, in the presence of a carbohydrate, leads to the formation of the tetranuclear complex of cobalt (III): [Co-4(NH3)(12)(OH)(6)](6+) partially resolved. ...
A comparison of charge-transfer mechanisms at rotated disk electrode for biomimetic binuclear and tetranuclear oxo-manganese complex in aqueous solution
(Elsevier B.V., 2015-01-30)
Many high-valence multinuclear mu-oxo-bridged manganese complexes have been synthesized to mimic the active site of the natural enzymes. The electrochemical and kinetic parameters were determined for two mimicking complexes ...
