Single crystals of diammonium tetranitratouranylate (NH4)2[UO2(NO3)4] (I) and a new diammonium tetranitratouranylate complex with 18-crown-6 [(NH4)(18C6)]2[UO2(NO3)4] (II) have been synthesized by the reaction of diaquadinitratouranyl tetrahydrate with ammonium nitrate in a nitric acid solution
and the reaction of the same reagents with 18C6 in an ethanol solution, respectively. The X-ray diffraction analysis of compounds
I and II has been performed. Crystals of compounds I and II are monoclinic, Z = 2, space group P21/n, a = 6.4075(5) ?, b = 7.7851(7) ?, c = 12.4461(12) ?, β = 101.239(1)°, V = 608. 94(9) ?3 for compound I and a = 10.542(9) ?, b = 8.590(8) ?, c = 22.5019(19) ?, β = 101.632(1)°, V = 2058.3(3) ?3 for compound II. The [UO2(NO3)4]2− complex anion in compounds I and II contains two monodentate and two bidentate cyclic nitrato groups, and the coordination number of uranyl is 6. The 18C6 molecule
in the structure of compound II has the classic crown conformation and combined with the ammonium ion by three hydrogen bonds. Compounds I and II formed by electrostatic attraction forces between counterions are stabilized by (NH4+)NH...O(NO3−) interionic hydrogen bonds. 相似文献

A new binuclear cadmium(II) complex with neutral ligands, 1,2-diaminobenzene (DMB) and dimethylformamide (DMF), [Cd2(Ph(NH2)2)5(DMFA)4](B10H10)2, was synthesized and studied by IR spectroscopy and X-ray diffraction. The crystals are monoclinic, a = 26.198(3) ?, b = 12.742(3) ?, c = 21.658(3) ?, β = 119.985(10)°, Z = 8, space group C2/c. The distorted octahedral environment of Cd is formed by four nitrogen atoms of three DAB molecules and two oxygen atoms
of DMF molecules. Three independent DAB molecules perform different functions: one chelates the Cd atom, another is linked
to cadmium as a monodentate ligand, and the third one bridges two Cd atoms, thus forming the dimer. The amino groups of the
DAB molecules are involved in the N-H⋯O and N-H⋯N hydrogen bonds and in N-H⋯B and N-H⋯H-B specific interactions with the cluster
boron anion.

The [Ni(DDM)2(NO3)2(H2O)2] complex (DDM is 4,4-diaminodiphenylmethane [CH2(C6H4NH2)2]) is synthesized, and its structure is determined. The crystals are triclinic, space group P
, a = 5.846(1) ?, b = 9.450(2) ?, c = 13.390(3) ?, α = 105.63(3)°, β = 98.13(3)°, γ = 105.84(3)°, V = 666.6(2) ?3, ρcalcd = 1.553 g/cm3, Z = 2. The Ni(II) ion (in the inversion center) is bound to a distorted octahedral array formed by the nitrogen atoms of the
primary amino groups of the DDM molecules and the oxygen atoms of the monodentate nitrato groups and water molecules (Ni(1)-N(3)
2.119(2) ?, Ni(1)-O(1) 2.122(2) ?, Ni(1)-O(w) 2.047(2) ?, angles at the Ni atoms vary in the 85.08(9)°–94.92(9)° interval).
The structure contains supramolecular metallacycles formed by the O(w)-H…N(2) hydrogen bonds between the coordinated H2O molecules and the terminal amino groups of DDM. The metallacycles are joined by the Ni2+ ions into infinite chains running in the [111] direction.

The thermolysis of the complexes [Co(NH3)6]2C2O4[Cu(C2O4)2]2 (I) and [Co(NH3)6]Cl[Cu(C7H4O3)2] (II) in air and hydrogen at 200, 350, and 500°C and the composition and properties of the thermolysis products are considered.
The oxidative thermolysis of the complexes yields mixtures of cobalt and copper oxides, including mixed ones. The reductive
thermolysis of the complexes yields a Co + Cu bimetallic powder in the case of compound I and a Co + Cu + C powder in the
case of compound II. The thermal behavior of the complexes is governed by the nature of the ligand coordinated to the copper
atom. The observed data are explicable in terms of the properties of this ligand. The chemistry of the oxidative and reductive
thermolysis is discussed.

(MoO4)1s-x
(x = 0, 0.5, 1) complex salts is shown, and their thermal properties are compared. In a hydrogen atmosphere, transformations
begin at T ∼ 200°C. According to the powder XRD data, the phase composition of the end products is markedly different. For the Rh—Mo
system, the dependence (V/Z) of the atomic volume on the composition is presented. The thermal decomposition product [Rh(NH3)5Cl](MoO4) (T

Influence of NH4F concentration on the conditions of separation of Ti(IV) and Fe(III) salts by fractional hydrolysis under the action of ammonia
in the system (NH4)2TiF6-(NH4)3FeF6-NH4F-H2O was studied. The coprecipitation of (NH4)3TiO2F5 and (NH4)3FeF6 as a result of crystallochemical substitution of Fe+3 for Ti+4 makes it possible to reduce the content of Fe(III) salts in the system. After separation of a precipitate containing up to
25% of Ti from solutions with NH4F concentrations from 10.6 to 22.3% and subsequent hydrolysis, the remaining titanium precipitates. The precipitate is annealed
up to 800°C in the presence of water vapor to form TiO2 with a whiteness above 92%.

The thermolysis of complexes [Co(NH3)6][Fe(CN)6] and [Co(NH3
6]4[Fe(CN)6]3 under an air or hydrogen atmosphere at 200, 350, and 500°C is studied. The composition and properties of thermolysis products
are determined. The oxidative thermolysis yields mixtures of oxides of the central metals; the reductive thermolysis yields
intermetallic compounds CoFe. The density of the complexes and the specific surface area of the intermetallic compounds are
measured. Average particle sizes are calculated. The morphology and dispersion of the powders are dictated by the shape and
density of the crystals of the precursor double salts and the thermolysis temperature. The thermolysis chemism in the oxidative
and reductive atmospheres is discussed in the context of the nature of the complex anion.

1-Allyl-4-aminopyridinium chloride reacts with Cu(NO3)2 · 3H2O in an ethanolic solution under the conditions of ac electrochemical synthesis at copper electrodes to form crystals of compound
[(NH2C5H4N(C3H5))2Cu3Cl3(NO3)2] (I). The crystals of compound I are monoclinic: space group P21/c, Z = 4, a = 25.770(7), b = 7.230(4), c = 12.505(5) ?, β = 92.58(3)°, V = 2328(2) ?3. The direct interaction of 1-allylquinolinium nitrate with Cu(NO3)2 · 3H2O in a methanolic solution in the presence of metallic copper yields crystals of compound [C9H7N(C3H5)Cu(NO3)2] (II).

. Each of two copper atoms (Cu(1) and Cu(2)) π-coordinates the C=C bonds of the allyl groups of the 1-allyl-4-aminopyridinium
cations, the oxygen atom of the nitrate ions, and two chlorine atoms. The third copper atom Cu(3) is linearly linked with
two chlorine atoms. Particular polymeric fragments are additionally joined by the N-H…O, C-H…O, C-H…Cl hydrogen bonds. The
crystal structure of compound II is built-up of the isolated L2Cu2(NO3)4 fragments (L is the 1-allylquinolinium cation). The metal atom is localized in the trigonal pyramidal coordination environment
of three oxygen atoms of the nitrate ions and of the C=C bond of the allyl group of the cation. The particular L2Cu2(NO3)4 fragments are additionally joined by the C-H…O hydrogen bonds.

Simultaneous electron diffraction and mass spectrometry along with a quantum chemical (DFT/B3LYP) calculation are applied
to study the molecular structure of yttrium tris-hexafluoroacetylacetonate Y(hfa)3. The superheating of the vapor in a double two-temperature effusion cell shows that up to a temperature of ∼200°C ions containing
from one to three metal atoms are formed, and the most intensive ion has the stoichiometry of (Y2L5)+ at a temperature below ∼120°C. The monomer starts to noticeably decompose at temperatures above 330°C.The electron diffraction
patterns of monomers are obtained at T
exp = 208(5)°C. According to the results of theoretical and experimental investigations, Y(hfa)3 molecule has D
3-symmetry. The rotation angle of triangular O-O-O faces with respect to their position in the regular prism is equal to 14.4(1)°C.
The values of internuclear distances and valence angles (r
h1-geometry) are: r(Y-O) = 2.259(6) Å, r(C-O) = 1.263(6) Å, r(C-Cr) = 1.413(4) Å, r(C-CF) = 1.531(4) Å, r(C-F) = 1.344(3) Å, O-Y-O = 75.2(2)°, O-C-CF = 113.8(2)°, C-CF-F = 112.4(2)°. The results of quantum chemical calculations are well consistent with the experimental data.

The interaction of the Co(iso-Bu2PS2)2 chelate with 4-NH2Py afforded a paramagnetic complex [Co(4-NH2Py)(iso-Bu2PS2)2] (μeff = 4.53 BM). Single crystals of [Ni(4-NH2Py)2(iso-Bu2PS2)2] (I) and [Co(4-NH2Py)(iso-Bu2PS2)2] (II) were grown and used for X-ray diffraction investigation (X8 APEX diffractometer, MoK
α radiation). Crystals I are monoclinic with unit cell parameters a = 12.5336(5) Å, b = 9.4356(4) Å, c = 16.4095(6) Å; β = 111.351(1)°; V = 1807.4(1) Å3; Z = 2, ρ = 1.223 g/cm3, space group P21/n.

. The structures of I and II are formed by isolated mononuclear molecules. The coordination unit is NiN2S4 (octahedron) in I and CoNS4 (tetragonal pyramid) in II. The 4-NH2Py molecule is coordinated through the N atom of the heterocycle. Electronic spectroscopy data for II agree with the symmetry of the NS4 polyhedron found by X-ray diffraction (XRD) analysis. The noncoordinated amine groups link the complex molecules via N-H...S
