Dimerization of the 2-(Methylselenomethyl)benzimidazole-silver(I) Cation Involving a AgI-AgIInteraction

Autor: Markus Leboschka, Stanislav Záliš, Mark Niemeyer, Wolfgang Kaim, Monika Sieger

Publikováno v: Zeitschrift für anorganische und allgemeine Chemie. 634:2343-2346

Reacting the bidentate ligand 2-(methylselenomethyl)-1H-benzimidazole (msb) with AgBF4 in CH3CN did not produce the expected [Ag(msb)2]+ ion with two five-membered chelate rings but the dimeric [Ag2(msb)2]2+, isolated and crystallized from acetonitri

Publikováno v: Inorganic chemistry. 46(14)

Complexes cis-MCI 2 (big), big = bis(1-methylimidazol-2-yl)glyoxal, M = Pt, Pd, were prepared and characterized through electrochemistry, spectroscopy, and for M = Pt, by X-ray structure analysis. The seven-membered chelate ring formed through N,N' c

Ancillary ligand determination of the spin location in both oxidised and reduced forms of diruthenium complexes bridged by bis-bidentate 1,4-bis(2-phenolato)-1,4-diazabutadiene
