Reaction of the OOO-coordinating tridentate bis(phenolate) protio-ligand 2,2'-{oxybis(methylene)}bis{4,6-di(1-methyl-1-phenylethyl)phenol} (L(O3)-H2), with 1 equiv. of KN(SiMe3)2 in toluene or THF yielded [K(L(O3)-H)] (1) or [K(L(O3)-H)(THF)] (2), respectively. Single-crystal X-ray diffraction studies of 1 and 2 revealed mononuclear structures with the phenyl rings of the bulky ligand displayin...

A pioneering research on a self-assembly of the magneto-anisotropic module [Re(CN)7] with the Mn(III) complexes involving Salen type (N,N′-ethylenebis(salicylideneiminate)) Schiff base (SB) ligands was performed using the known [Mn(Salen)(H2O)2]2(ClO4)2·H2O (1) and the firstly synthesized [Mn2(Salen)2OAc]PF6 (2). In the case of 1, a slow diffusion of the component solutions led to the ionic com...

Abstract. During a research flight of the Wave-driven ISentropic Exchange (WISE) campaign, which was conducted over eastern North Atlantic on 1 October 2017, composition upper troposphere and lower stratosphere (UTLS) across jet stream observed by airborne, range-resolved differential absorption lidar (DIAL) profiles. We investigate how high variability in paired H2O O3 distribution along two-d...

Three barrel-shaped artificial molecular capsules 1-3, based on normal cucurbit[5]uril (Q[5]) and decamethylcucurbit[5]uril (Me10Q[5]), were synthesized and structurally characterized by single-crystal X-ray diffraction. Encapsulation of a chlorine anion in the cavity of a Q[5] or Me10Q[5] to form closed a molecular capsule with the coordinated metal ions or coordinated metal ions and water mol...

The hydrazine s-triazine ligand (E)-4,4’-(6-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)-1,3,5-triazine-2,4-diyl)dimorpholine (DMPT) was used to synthesize two new Ni(II) complexes via a self-assembly technique. were synthesized by one-pot synthesis strategy and characterized elemental analysis, FTIR single-crystal X-ray diffraction analysis be [Ni(DMPT)(H2O)3](NO3)2.3H2O (1) [Ni(DMPT)(H2O)3](NO3...

The inhibitory effect of benzoic acid hydrazide (bah) and 3-methoxybenzoic acid hydrazide (mbah) on Saccharomyces cerevisiae strains has been compared to that of their platinum(II) complexes: cis-[Pt(mbah)2X2], cis-[Pt(NH3)(mbah)Cl2].0.5 H2O, cis-[Pt(mbah)2X2] and cis[Pt(NH3)(mbah)Cl2] (mean = Cl, Br = I), and cis-[Pt(NH3)2Cl2]. The minimal inhibitory concentrations for bah and mbah were 5000-2...

The phenalenyl-based dysprosium complexes [Dy(PLN)2(HPLN)Cl(EtOH)] (1), [Dy(PLN)3(HPLN)]·[Dy(PLN)3(EtOH)]·2EtOH (2) and [Dy(PLN)3(H2O)2]·H2O (3), HPLN being 9-hydroxy-1H-phenalen-1-one, have been synthesized. All compounds were fully characterized by means of single crystal X-ray analysis, paramagnetic (1)H NMR, MALDI-TOF mass spectrometry, UV-vis spectrophotometry and magnetic measurements. Bo...

In this work, hydrogen-bonding interactions between apigenin and water/ethanol were investigated from a theoretical perspective using quantum chemical calculations. Two conformations of apigenin molecule were considered in this work. The following results were found. (1) For apigenin monomer, the molecular structure is non-planar, and all of the hydrogen and oxygen atoms can be hydrogen-bonding...
