Nafion films incorporating cationic nickel complexes [Ni(II)(acac)(R4en)](+) (acac = acetylacetonato, R4en = tetraalkylethylenediamine) that exhibit chromic behavior in response to temperature changes and solvent molecules in the vapor and liquid phases have been prepared.

Many attempts to obtain single crystals appropriate for X-ray diffraction analysis of the Ln(tpp)(acac) derivatives (where Ln = Gd or Sm, tpp = tetraphenylporphyrin and acac = acetylacetonate) have failed so far. A suitable way to get structural parameters for these monoporphyrinates is to use extended X-ray absorption fine structure (EXAFS) spectroscopy. We recorded spectra of the monoporphyri...

The solubility of tris(pentane-2,4-dionato)chromium(III) (Cr(acac)(3)) in supercritical carbon dioxide (SC-CO(2)) containing organic modifiers (1,1,1,3,3,3-hexafluoro-2-propanol (HFP) and 3,5-bis(trifluoromethyl)phenol (BTMP)) of hydrogen-bond donors was investigated by UV/VIS spectrophotometry. A great solubility enhancement of Cr(acac)(3) in SC-CO(2) was accomplished by adding HFP and BTMP. T...

Iridium complexes were synthesized on MgO powder by adsorption of Ir(C(2)H(4))(2)(acac) [acac = acetonylacetonate]; images determined by aberration-corrected scanning transmission electron microscopy show individual Ir atoms, demonstrating that the supported complexes were site-isolated.

Mononuclear and dinuclear ruthenium(III) complexes with bis-β-diketonato ligands (denoted by [Ru(acac)(2)(L-LH)] and [Ru(acac)(2)(L-L)Ru(acac)(2)], respectively) were synthesized, where acac, L-LH(-) and L-L(2-) denote acetylacetonato, monoprotonated and unprotonated bis-β-diketonato ligands, respectively. The following three ligands were used as the bis-β-diketonato ligand (L-L(2-)): 1,2-diace...

An efficient stepwise synthesis method for discovering new heteromultinuclear metal clusters using a robotic workflow is developed where numerous reaction conditions constructing oxo in polyoxometalates (POMs) were explored custom-built automated platform. As result, nonanuclear tetrametallic {FeMn4}Lu2A2 TBA5[(A-α-SiW9O34)2FeMn4O2{Lu(acac)2}2A2] (IIA; A = Ag, Na, K; TBA tetra-n-butylammonium; ...
