Syntheses and Molecular Structure of [Mg₂(OR)₄(AlMe₃)₂] and [ZrCl₃(OR)₂(AlMe₂)] (OR = 1-methoxy-2-propoxide)

Abstract

The magnesium dicubane-like species [Mg 4 -(OR) 8 ] (1, 99%) react with AlMe 3 to form [Mg 2 (OR) 4 -(AlMe 3 ) 2 ] (2, 58%), which react with ZrCl 4 to give [ZrCl 3 (OR) 2 (AlMe 2 )] (3, 43%).

Solubilities, Structures, and Speciations of Bimetallic Composite Ionic Liquids: X-ray Absorption Fine Structure and Density Functional Theory Calculations

“…The detailed fitting parameters are listed in Table . Similar to Cu-ILs, the first peak emerging at ∼2.5 Å was attributed to Zr–Cl, agreeing with the other XAFS results , and single-crystal results. ,− Seven chlorine ligands encompassed the zirconium center, larger than the Cu–Cl shell (two), owing to its larger atom radii. The latter peak appeared at ∼3.8 Å was assigned to Zr–Al (Cl bridged), which was reasonably different from that of Zr–Zr (3.087–3.428 Å) and Zr–Cl–Zr (3.622 Å) .…”

Well-defined polynuclear heterobimetallic complexes as precursors for ceramic and magnetic materials

“…25 Among these methods one of the less explored is a reaction of organometallic complexes with alkoxides that bear free alcohols at the metal site as shown in Scheme 2. [26][27][28][29][30][31][32][33][34][35][36] Scheme 2 A route to mixed-metal alkoxides utilizing organometallics. This Perspective article describes our results that were obtained by exploring this simple and, in our opinion, very underestimated approach.…”

A pentanuclear bimetallic complex of manganese(II) and aluminium(III) ions: tetra-μ2-iodido-iodidobis(μ3-2-methoxyethanolato)bis(μ2-2-methoxyethanolato)dimethyl(tetrahydrofuran-κO)aluminium(III)tetramanganese(II)

“…Alkylaluminum alkoxides have been investigated as components of Ziegler±Natta catalyst systems (Lin et al, 1999;Rhine et al, 1999;Sobota, 2004;Lewinski et al, 2005). To date, several heterometallic aluminium complexes have been synthesized and characterized (Evans et al, 1998;Sobota et al, 2000Sobota et al, , 2002Utko et al, 2004;Jerzykiewicz et al, 2006). In a continuation of our systematic study in this ®eld, a new heterometallic aluminium complex with functional alcohols has been prepared.…”
