Double complex salts (DCS) [RuNO(NH3)4(H2O)]2[MCl4]Cl4·2H2O, M = Pt (I) and Pd (II), are prepared and characterized using IR spectroscopy, single crystal and powder X-ray diffraction, and thermogravimetric analysis. Crystalline phases of I and II are isostructural (P2(1)/n space group) and have the following crystallographic characteristics: a = 6.689 Å, b = 15.609 Å, c = 12.348 Å, V = 1289.1 Å3, Z = 2, d x = 2.425 g/cm3 (I) and a = 6.637 Å, b = 15.521 Å, c = 12.244 Å, V = 1261.2 Å3, Z = 2, d x = 2.255 g/cm3 (II). The thermolysis of the obtained DCS in the hydrogen atmosphere affords two-phase mixtures of limited solid solutions of the metals: hcp for ruthenium-based ones and fcc for Pt or Pd based solutions. On decomposition in the helium atmosphere the products contain a minor amount of RuO2. For the phases obtained during thermolysis the parameters are determined and the compositions are estimated. The heating of I to 400°C in the helium-air atmosphere yields a nanocrystalline composite Pt+RuO2 with CSR of ~20 nm. 相似文献

Two complexes with similar compositions are synthesized: (18-crown-6)(nitrato-O,O′)potassium (I) and (18-crown-6)(nitrato-O,O′)potassium(0.91)silver(0.09) (II). Their isomorphic orthorhombic crystals (space group P212121, Z = 4) are studied by X-ray diffraction analysis. Structure I (a = 8.553 Å, b = 11.967 Å, c = 17.871 Å) and structure II (a = 8.540 Å, b = 11.956 Å, c = 17.867 Å) are solved by a direct method and refined by the full-matrix least-squares method in the anisotropic approximation to R = 0.044 (I) and 0.055 (II) for all 2385 (I) and 2379 (II) measured independent reflections. Complex molecules [K(NO3)(18-crown-6)] in structure I and [K0.91Ag0.09(NO3)(18-crown-6)] in compound II are of the host-guest type and rather similar in structure. Their 18-crown-6 and NO 3 ? ligands are disordered over two orientations. The K+ cation in complex I and the mixed cation (K0.91Ag0.09)+ in complex II reside in the cavity of the disordered 18-crown-6 ligand and is coordinated by its six O atoms and by two disordered O atoms of the NO 3 ? . ligand. The coordination polyhedron (CN = 8) of the K+ cation in complex I and that of (K0.91Ag0.09)+ cation in complex II is a distorted hexagonal pyramid with a base of six O atoms of the 18-crown-6 ligand and a split vertex at two O atoms of the NO 3 ? ligand. 相似文献

The complexes [AgL2(NO3)] (I) and [AgL2(CH3SO3)] · H2O (II) (L is 2-methylquinoline, C10H9N) have been synthesized and structurally characterized by single-crystal X-ray diffraction. Crystals of I are monoclinic, space group P21/n, a = 9.296(1) Å, b = 13.495(1) Å, c = 14.931(1) Å, β = 95.06(1)°, V = 1865.8(3) Å3, ρcalc = 1.624 g/cm3, Z = 4. Crystals of II are monoclinic, space group P21/n, a = 13.147(1) Å, b = 11.767(1) Å, c = 13.814(1) Å, β = 96.06(1)°, V = 2124.3(3) Å3, ρcalc = 1.599 g/cm3, Z = 4. Compounds I and II are composed of discrete complexes of similar structure but with different orientation of the methyl groups of ligand L (trans and cis arrangement, respectively). Both anions, NO 3 - and CH3SO 3 - function as a chelating weakly bound ligand for the Ag+ ion. The presence of water molecules in II is favorable for the formation of dimeric supramolecular moieties between the centrosymmetrically arranged Ag+ complexes with 2-methylquinoline. The luminescence spectra of solid complexes I and II showed a bathochromic shift as compared to the spectrum of L in acetonitrile. Complexes I and II have been characterized by 1H and 13C{H} NMR spectra in CD3CN. 相似文献

Two new complexes were synthesized, namely, 7: 2 (2.2.2-cryptand)potassium chloride and (2.2.2-cryptand)ammonium bromide(0.75)chloride(0.25) hydrates: [M(Crypt-222)]+ · Hal? · 3.5H2O, where M = K, Hal = Cl (I) and M = NH4, Hal = Br0.75Cl0.25 (II). The structures of two isomorphous crystals were studied by X-ray diffraction analysis. Trigonal (space group P \(\bar 3\), Z = 2) structures I (a = 11.763 Å, c = 11.262 Å) and II (a = 11.945 Å, c = 11.337 Å) were solved by direct methods and refined by the full-matrix least-squares method in the anisotropic approximation to R = 0.057 (I) and 0.065 (II) for all 2626 (I) and 1654 (II) independent measured reflections (CAD-4 automated diffractometer, λMoK α). In structures I and II, the host-guest [M(Crypt-222)]+ complex cation lies on the threefold crystallographic axis and has the approximate D 3 symmetry. In complex I, the coordination polyhedron of the K+ cation (CN = 8) is a bicapped trigonal prism somewhat distorted toward an antiprism. Complexes I and II contain H-bonded disordered cubes of the water molecules and the Cl? or Br? anions. 相似文献

In crystals of complexes I and II, the [Rb(Crypt-222)]+ cation of the host-guest type lies on the crystallographic axis 3 and has the approximate symmetry D 3. In complexes I and II, the coordination polyhedron of the Rb+ cation is a two-base-centered trigonal prism somewhat distorted to an antiprism.

Single crystal X-ray diffraction is used to investigate two synthesized β-diketonate complexes of copper(II) with aminopyridine: Cu(4-NH2Py)(aa)2 (I) and Cu(4-NH2Py)(hfa)2 (II). The crystals of I and II have a monoclinic system; the unit cell parameters of I are: P21/n space group, a = 8.2921(3) Å, b = 14.7243(5) Å, c = 13.4970(4) Å, β = 102.426(1)°, V = 1609.32(9) Å3, Z = 4; for II: C2/c space group, a = 23.5704(5) Å, b = 11.4977(2) Å, c = 16.0285(3) Å, β = 109.265(1)°, V = 4100.6(1) Å3, Z = 8. The structures of I and II are molecular; they are composed of isolated molecules. The coordination polyhedron of the copper atom is formed by the O atoms of two acetylacetonate ligands (Cu-O 1.940(2)–2.171(2) I and the O atoms of two hexafluoroacetylacetonate ligands (Cu-O 1.940(2)–2.215(3) Å) in II. The molecules of 4-NH2Py are bonded to the copper atom via the nitrogen atom of the aromatic ring (Cu-N 2.008(2) Å in I and Cu-N 1.978(3) Å in II).

Two complexes, namely, triaqua(18-crown-6)strontium dibromide monohydrate (I) and diaquabromo(18-crown-6)barium bromide (II), are synthesized. Their crystal structures are determined by X-ray diffraction analyses. For complex I, space group C2/c, a = 17.547 Å, b = 10.246 Å, c = 14.786 Å, β = 123.08°, Z = 4. For complex II, space group Pnma, a = 17.753 Å, b = 17.465 Å, c = 6.629 Å, Z = 4. The structures are solved by a direct method and refined by the full-matrix least-squares method in the anisotropic approximation to R = 0.056 (I) and 0.042 (II) for 2696 (I) and 2440 (II) independent reflections (CAD-4 automated diffractometer, λMoK α radiation). Both complex cations—randomly disordered [Sr(18C6)(H2O)3]2+ in complex I and [BaBr(18C6)(H2O)2]+ in complex II—are of the host-guest type. The Sr2+ (Ba2+) cation resides in the cavity of the 18-crown-6 ligand and coordinated by all six O atoms. In the structures complexes I and II, the coordination polyhedra of the Sr2+ and Ba2+ cations (coordination number 9) can be described as distorted hexagonal bipyramids with one apex at the O atom of the water molecule in complex I or at the Br? ligand in complex II and the other split apex at the O atoms of two water molecules. 相似文献

Iron(III) and aluminum(III) complexes with 2-diphenylacetyl-1,3-indandione (HL) have been synthesized. The structures of the obtained compounds FeL3(I) and AlL3(II) were studied. The isostructural crystals are monoclinic, I: Z = 8, space group P21/c, a = 16.061(3) Å, b = 16.658(3) Å, c = 22.015(4) Å, β = 111.41(3)°; II: Z = 8, space group P21/c, a = 16.115(14) Å, b = 16.476(8) Å, c = 21.949(20) Å, β = 111.04(11)°. The structural units of crystals I and II are neutral molecules in which each ligand is bidentately coordinated to a central metal atom through the oxygen atom of the acyl keto group and an oxygen atom of the indandione fragment to form a six-membered chelate ring. In the crystals, neutral molecules I and II form pseudodimers due to stacking of indandione moieties of two adjacent coordination spheres and additional C-H…O contacts. Each pseudodimer is in contact with six neighboring dimers also through hydrogen bonds C-H…O to form an infinite framework. 相似文献
