“…In addition, the IR spectrum of 4 revealed two bands at 1534 and 1342 cm –1 ascribed to ν a (OCO) and ν s (OCO) stretches, respectively. The Δν = ν a (OCO) – ν s (OCO) value of 192 cm –1 supports the presence of a hydrogen bonded monodentate acetate coordination mode as found in the solid state (see above) . An intense band was also observed at 2033 cm –1 for 5 which is ascribed to the ν(N 3 ) stretch.…”

Three symmetrical N,N′,N′′-triarylguanidinatoruthenium(II) complexes, [(η 6 -p-cymene)RuCl{κ 2 (N,N′)((ArN) 2 C-N(H)Ar)}] (Ar = 2-(CF 3 )C 6 H 4 (1), 4-(CF 3 )C 6 H 4 (2) and 3,5-(CF 3 ) 2 C 6 H 3 (3)) were isolated in good yields. The reaction of 3 with NaOAc, NaN 3 and KSCN afforded [(η 6 -p-cymene)RuX{κ 2 (N,N′)((ArN) 2 C-N(H)Ar)}] (X = OAc (4), N 3 (5) and an admixture of SCN (6) and NCS (7)) respectively in very good yields. On the other hand, metathesis reaction of 3 with AgSbF 6 in the presence of MeCN afforded [(η 6 -pcymene)Ru(MeCN){κ 2 (N,N′)((ArN) 2 C-N(H)Ar)}][SbF 6 ] (8) in good yield. Complex 5 upon treatment with diethylacetylenedicarboxylate and bis(diphenylphosphanyl)acetylene separately afforded [a]

“…The sol-gel deposition 2 method 6 is routinely used, but the details of the process are still controversial. Some works demonstrate the huge influence that ambient humidity 7 , precursor 8 or solvent 9 have on the pyrolysis of zinc acetate dihydrate (ZAD) and the subsequent formation of ZnO 10,11,12 . Other reports highlight the appearance of different intermediate compounds, such as hydroxyl-or anhydrous acetates 13 , oxo-acetates 14 or hydrated hydroxyl-acetates 15 when similar ZAD species degrade, giving rise to nanowires 16 , nanobelts 17 or other nanostructures 18,19,20 .…”

Abstract:The processes involved in the assembly of zinc acetate dihydrate {Zn(CH 3 COO) 2 ·2H 2 O} and ethanolamine (H 2 NCH 2 CH 2 OH), with or without 2-methoxyethanol as solvent, have been analysed by infrared spectra, mass spectrometry, nuclear magnetic resonance, powder X-ray diffraction and computational studies. Thermal evolution of the mixtures was characterized by thermoanalytical and structural techniques (thermogravimetry, differential thermal analysis, differential scanning calorimetry, X-ray diffraction and X-Ray photoelectron spectroscopy). Computational studies together with experiments served to thoroughly describe the precursor and its decomposition. The thermal decomposition of the mixture and its transformation into crystalline ZnO take place in a temperature range between 50 and 450 °C through different processes. With solvent, the processes need temperatures

“…For example, the monomeric complex of zinc pivalate occasionally contains chelating and bridging pivalato ligands with SP geometry (6, R = t-Bu) in the crystal structure. [18] Quadruplex-bridged dinuclear Zn complexes 7 with various carboxylato ligands have been crystallographi-cally determined (R = methyl, crotyl, and aryl), [18][19][20][21] and the highly symmetric structure of 7 has allowed the design of PCPs/ MOFs as SBUs. [22] Linear polymeric triple-bridged dinuclear Zn complexes 8 crosslinked by another bridging carboxylato ligand has also been reported (R = 2,4,6-trimethylphenyl) [23] and used as SBUs.…”

Zinc carboxylate complexes are widely utilized as artificial models of metalloenzymes and as secondary building units of PCPs/MOFs. However, the relationship between the structure of the monodentate carboxylato ligand and the molecular arrangement of multinuclear zinc carboxylate complexes is not fully understood because of the coordination flexibility of the Zn ion and carboxylato ligands. Herein, we report the structural analysis of a series of complexes derived from zinc (meth)acrylate which has a linear infinite chain structure. The molecular structure of μ4‐oxido‐bridged tetranuclear complexes [Zn4(μ4‐O)(OCOR)6] revealed a distorted Zn4O core. Crystallization of zinc acrylate under aqueous conditions afforded a μ3‐hydroxido‐containing pentanuclear complex [Zn5(μ3‐OH)2(OCOR)8] as the repeating unit of an infinite sheet‐like structure in the solid state. It was also obtained by the hydrolysis of the μ4‐oxido‐bridged tetranuclear complex. In sharp contrast, the methacrylate analog retained the methacrylato ligands under aqueous crystallization conditions to form a macrocyclic dodecanuclear complex with methacrylato as the sole ligand.
