The reaction of lucigenin (Lc) with potassium hexacyanoferrate is accompanied by the appearance of charge-transfer bands in the visible spectral region and yields Lc{H}2[Fe(CN)6] · 4H2O in an acidic medium and Lc4[Fe(CN)6](NO3)5 · 18H2O in a neutral medium in air. 相似文献

Novel mononuclear cymantrenecarboxylate complexes of transition metals, [Co(H2O)6](CymCO2)2·4H2O (Cym = (η5-C5H4)Mn(CO)3) (1), [Ni(H2O)6](CymCO2)2·4H2O (2), [Zn(H2O)6](CymCO2)2·4H2O (3), [Co(CymCO2)2(imz)2] (imz = imidazole, 4), [Co(CymCO2)2(bpy)2]·2PhMe (bpy = 2,2′-bipyridyl, 5), [Ni(CymCO2)(bpy)2(H2O)][CymCO2]·0.5MePh·2H2O (6), [Cu(CymCO2)2(imz)2] (7), and [Cu(CymCO2)2(bpy)(H2O)] (8), were obtained and characterized by single-crystal X-ray analysis. Complexes 1–3 are isostructural. Magnetism of the Co complexes 1, 4, and 5 was studied; it was shown that they exhibit the properties of field-induced single-molecule magnets with magnetization reversal barriers (ΔE/kB) of 44, 13, and 10 K, respectively. Thermal decomposition of complexes 1–8 was studied by means of DSC and TGA methods. The final products of thermolysis of 1–6 in air, according to powder XRD data, are the pure spinel phases MMn2O4; for the cases of copper complexes, the mixtures of CuMn2O4 and CuO were found in the products. 相似文献

Coordination polymers of REEs with 2-aminoterephthalic acid [Ln2(C8H5NO4)3(H2O)5] n · 2nH2O (Ln = Eu, Gd, or Tb) and [Y2(C8H5NO4)3(H2O)4] n · 4nH2O were prepared by hydrothermal synthesis. Studies of the thermal behavior of these coordination polymers have shown that the removal of the solvate and the coordinated water molecules occurs at heating to 250°C and dehydratation products are stable up to 400°C. Detailed studies of the magnetic behavior of Eu, Gd, and Tb polymers were performed. 相似文献

Compounds [HBipy][Y(NCS)4(Bipy)2] · H2O (I), [HPhen][Y(NCS)4(Phen)2] (II), and [Y(Nic)3(H2O)2]2 (III), where Bipy is 2,2′-bipyridine and Phen is 1,10-phenanthroline, are synthesized and structurally characterized by X-ray diffraction analyses (CIF files CCDC 984621, 984622, and 934971, respectively). In the anionic complexes, the coordination polyhedron of sodium is formed by eight nitrogen atoms, four of which are provided by the acido ligands and four others are given by two molecules of the N-heterocycle. In compounds I and II, the protonated and coordinated diimines together participate in stacking interactions. 相似文献

The structure and ion-selective properties of some 2-phosphorylphenols were studied. It was shown that, irrespective of the nature of the substituents on the benzene ring and on the phosphorus atom, these compounds exhibit potentiometric selectivity to cesium cation. The crystal structures of 2-(diphenylphosphoryl)-4-ethylphenol and 2-[(diphenylphosphoryl)methyl]phenol were established. 相似文献

The reaction of indium thiocyanate with bipyridine (4,4-Bipy) and urotropine (Ur) gave [H2(4,4′-Bipy)][In(H2O)2(NCS)4]2 (I) and [HUr]2[In(H2O)(NCS)5] · 2H2O (II), which were identified using elemental analysis, IR spectra, and thermogravimetric analysis. The thermal decomposition of
compound I and II ends at 650 and 640°C, respectively, and gives In2O3. X-Ray diffraction analysis of compound I showed that complex anions in the crystal form chains through O-H…S hydrogen bonds. The anion chains form a close packing
of columns with bipyridine cations located in the voids.

A low-solubility complex [PbBipy2]6[Fe(CN)6]4 · Bipy · 14H2O was prepared and characterized by physicochemical methods. Although containing [PbBipy2]2[Fe(CN)6] discrete species and a {[PbBipy2][Fe(CN)6]}
n
infinite chain in the crystal structure, the complex has weak antiferromagnetic properties over a wide temperature range.
The irreversible thermal destruction of the complex, which starts at 192°C, is preceded by complete dehydration. 相似文献

The [WOCl3{PhNHC(O)CHC(O−)Me}] complex has been synthesized, and its crystal structure has been determined. The coordination polyhedron of the tungsten
atom is a distorted octahedron with a meridional arrangement of three chlorine atoms. Two oxygen atoms of the acetoacetanilide
bidentate chelating ligand occupy trans positions to the O(3) oxo atom and the Cl(3) atom. The crystal structures and the IR spectra of the WOCl3{PhNHC(O)CHC(Ot-)Me} and [MoO2Cl2{(o-MePh)NHC(O)CH2C(O)Me}] complexes are compared. 相似文献
