New heteroleptic magnesium complexes for MgO thin film application

Abstract

Novel heteroleptic magnesium complexes, [Mg(dmamp)(acac)]2 (), [Mg(dmamp)(tmhd)]2 (), [Mg(dmamp)(tfac)]2 (), and [Mg(dmamp)(hfac)]2 (), were successfully synthesized using dmamp and β-diketonate as ligands. The thermogravimetric analyses and volatile studies of the complexes showed that the complexes and display high volatility and thermal stability. The single crystal X-ray study of the complexes reveals that both the complexes and were crystalized in the triclinic space group and as dimers, where magnesium atoms are in the pentacoordinate state with distorted trigonal bipyramidal geometry.

Novel Heteroleptic Tin(II) Complexes Capable of Forming SnO and SnO2 Thin Films Depending on Conditions Using Chemical Solution Deposition

“…Complexes 1 and 2 crystallized in the monoclinic space group, whereas complexes 3 – 5 crystallized in the triclinic space group (Table ). All complexes formed essentially centrosymmetric dimers with aminoalkoxide oxygen bridging the two metal centers in the complexes via μ 2 –O bonding, similar to the bonding pattern of other metal complexes (Mg, Sr, In, Co, Zn) containing aminoalkoxide reported previously. − In the case of compounds 3–5 , they are also located on crystallographic centers of inversion. All structures have a four-membered Sn 2 O 2 core ring.…”

Germanium Compounds Containing Ge═E Double Bonds (E = S, Se, Te) as Single-Source Precursors for Germanium Chalcogenide Materials

“…GeCl 2 ·dioxane, KSeCN, n -BuLi (2.5 M in hexane), dimethylamine (2.0 M in tetrahydrofuran (THF)), and sulfur, selenium, and tellurium powders were purchased from Aldrich. Lithium 1-(dimethylanimo)-2-methylpropane-2-thiolate (Li­(dmampS)) was synthesized using a modified literature method. , Functionalized bidentate aminoalcohol, 1-dimethylamino-2-methyl-2-propanol (dmampH), (CH 3 ) 2 NCH 2 C­(CH 3 ) 2 OH, and sodium (1-dimethylamino-2-methyl-2-propoxide) (Na­(dmamp)) were prepared according to literature procedures. , Ge­(dmamp) 2 was synthesized using a modified literature method…”

Heteroleptic magnesium complexes containing amidinate and aminoalkoxy ligands

“…All carbodiimides (N,N 0 -diisopropylcarbodiimide, N-(tert-butyl)-N 0 -ethylcarbodiimide, and N,N 0 -di-tert-butylcarbodiimide) as well as MeMgBr (3.0 M solution in Et 2 O) were purchased from Sigma-Aldrich. Functionalized bidentate aminoalcohol, 1-dimethylamino-2-methyl-2-propanol (dmampH) [10,11] and Na(dmamp) [12] was synthesized by slight modification of the literature methods. 1 H NMR and 13 C NMR spectra were recorded on Bruker DPX 300 MHz FT-NMR spectrometer.…”
