Using different synthetic procedures four complexes [Fe2Cl4(5dmbpy)2] (1), [Fe(acac)Cl2(5dmbpy)] (2), [Fe(5dmbpy)3][Fe2Cl6O] (3) and [Fe(5dmbpy)3][Fe2Cl6O]·CH3CN (4) (5dmbpy is 5,5'‐dimethyl‐2,2'‐bipyridine, acac acetylacetonate) were prepared characterized. Complex 1 built up of dinuclear molecules in which two pentacoordinate Fe(II) central atoms are linked by a pair chloride ligands coordination completed chelating 5dmbpy terminal ligand. 2 exhibits molecular structure the...
The mononuclear tetracoordinate [Co(dmphen)X 2 ] (dmphen = 2,9‐dimethyl‐1,10‐phenanthroline neocuproine; X Cl, Br, I) complexes were prepared by a solvothermal method. X‐ray diffraction experiments showed that they possess analogous molecular structures, even though the chlorido complex crystallizes in different crystal system and space group. structures of are stabilized π–π interactions. Alternating‐current (AC) susceptibility measurements show bromido iodido behave as field‐induced...
A solvothermal reaction of Zn(ii) salt with methanetetrabenzoic acid (H4MTB) and 1,4,8,11-tetraazacyclotetradecane (cyclam, CYC) created a new microporous metal-organic framework {[Zn2(μ4-MTB)(κ(4)-CYC)2]·2DMF·7H2O}n (DMF = N,N'-dimethylformamide). Single crystal X-ray diffraction showed that the complex exhibits four-fold interpenetrated diamond-like structure topology 1D jar-like channels sizes about 14.1 × 2.4 Å(2). The stability activation conditions compound have been studied by...
Two tetranuclear [Zn4Cl2(ClQ)6]·2DMF (1) and [Zn4Cl2(ClQ)6(H2O)2]·4DMF (2), as well three dinuclear [Zn2(ClQ)3(HClQ)3]I3 (3), [Zn2(dClQ)2(H2O)6(SO4)] (4) [Zn2(dBrQ)2(H2O)6(SO4)] (5), complexes (HClQ = 5-chloro-8-hydroxyquinoline, HdClQ 5,7-dichloro-8-hydroxyquinoline HdBrQ 5,7-dibromo-8-hydroxyquinoline) were prepared possible anticancer or antimicrobial agents characterized by IR spectroscopy, elemental analysis single crystal X-ray structure analysis. The stability of the in solution was...
Trinuclear Ag(I) (1) and dinuclear mononuclear Zn(II) isonicotinate (2 3) complexes were prepared characterized by X-ray crystallography, elemental analysis, IR spectroscopy, thermal analysis. Single-crystal analysis of the complex reveals two different monodentate carboxylate coordination modes, protonated deprotonated, respectively. spectra showed correlations between modes Δ(νas − νs)IR values. In addition, hydrogen bonds significantly influence a position absorption bands. Moreover, IC50...
Abstract A novel holmium‐based porous metal‐porphyrin framework, {(H 3 O + )[Ho(H 2 TPPS)] − ⋅ 4H O} n (denoted as UPJS‐17 ), was synthesised by hydrothermal reaction. Structural analysis reveals, that has a three‐dimensional open framework. The framework is negatively charged and the negative charge compensated hydronium cation. compound showed no N adsorption but Ar, CO H . From argon adsorption, surface area of ~150 m g −1 determined. Carbon dioxide measured at various temperatures (0,...
A new iron(III) complex (Et3NH)2[Fe(L)2](ClO4)·MeOH (1) where H2L = 2-{(E)-[2-hydroxyphenyl)imino]methyl}phenol has been synthesised and characterised by single crystal XRD, elemental analysis DC magnetic susceptibility measurements. The dianionic ligands L2− coordinate in a tridentate fashion with the Fe(III) through their deprotonated phenolic oxygens azomethine nitrogen atoms, resulting trans-FeO4N2 chromophore. Variable-temperature measurements were performed between 300 5 K under an...
Asymmetrical Fe( iii ) Schiff base complexes, with N 4 O 2 coordination nature, exhibiting abrupt spin crossover a wide hysteresis loop of 27 K, were synthesised and characterised by SCXRD, SQUID magnetic measurements Mössbauer spectroscopy.
