The double complex salts [Ru(NH3)5Cl][PtCl6] (I) and [Ru(NH3)5Cl]2[PtCl6]Cl2 (II) were synthesized and studied by X-ray diffraction. They were found to be isostructural to the previously synthesized [Rh(NH3)5Cl][OsCl6] and [Ir(NH3)5Cl]2[PtCl6]Cl2. The thermolysis of the complexes in the atmosphere of hydrogen and helium was studied by the powder X-ray diffraction analysis.
The product of the salt I thermolysis is a single-phase solid solution Ru0.5Pt0.5 (a = 3.857(3) ?), the thermolysis of salt II results in a double-phase metallic powder.

Triphenylbismuth diaroxides Ph3Bi(OAr)2 (Ar = C6H3(Br2-2,4) (I), C6H2(Br2-2,6)(NO2-4) (II), and C6H2[(NO2)3-2,4,6] (III) are synthesized in yields up to 74% by the reaction of triphenylbismuth with phenols in the presence of hydrogen peroxide
(taken at a molar ratio 1: 2: 1, respectively) in ether. According to X-ray diffraction data, the bismuth atoms in compounds
I-III have distorted trigonal-bipyramidal coordination with the aroxyl substituents in the axial positions; the Bi-C, Bi-O bond
lengths and the OBiO, CBiC angles vary in the intervals 2.162–2.204, 2.150–2.299 ? and 172.4°–176.1°, 109.6°–139.9°, respectively.
Compound II exhibits intramolecular contacts between the central atom and ortho-Br atoms (3.924, 4.101 ?), and compound III has similar contacts of the Bi atom with the O atoms of the ortho-nitro groups (3.114, 3.313 ?).

I, II, and III (R-3, P21/c, and Pnnm space groups respectively) have the following crystallographic characteristics: a = 10.9804(2) ?, b = 10.9804(2) ?, c = 10.8224(3) ?, V = 1130.03(4) ?3, Z = 3, d

the bcc parameter a = 2.852 ? for I and a heterogeneous mixture of Co and Cu in the decomposition of II. The coordinated CN− and C2O42− groups then turn into NH3, hydrocarbons, and CO2. The dominant hydrocarbon is methane. 相似文献

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

Four Co(II) complexes, [Co(HL)2](OAc)2, [Co(HL)2Cl2], [Co(HL)2(MeOH)2](NO3)2, and [Co2(HL)4(SO4)2] (HL = acetone-N(4)-phenylsemicarbazone) were synthesized and characterized by physicochemical and spectroscopic methods. The magnetic susceptibility
measurements indicate that the complexes are paramagnetic with three unpaired electrons. In all the complexes, the semicarbazone
is coordinated as a neutral bidentate ligand. The structure of [Co(HL)2(MeOH)2](NO3)2 was confirmed by single crystal X-ray crystallography. The ligand is neutral and bidentate, being coordinated to the cobalt
atom through the carbonyl oxygen and the azomethine nitrogen. Intermolecular hydrogen bonding and C–H···π interactions combine
to stabilize the crystal structure. The ligand and its two complexes [Co(HL)2Cl2] and [Co(HL)2(MeOH)2](NO3)2 were screened for their antibacterial and antifungal activities using disk diffusion methods. 相似文献

A phase diagram for the hexane-[Y(NO3)3(TBP)3]-acetonitrile (1-2-3) liquid ternary at T = 298.15 K was studied. This ternary consists of two pairs of incompletely miscible liquids (hexane-acetonitrile and [Y(NO3)3(TBP)3]-hexane). It contains two homogeneous liquid fields and one two-phase liquid field. One phase is depleted of acetonitrile
and contains variable proportions of [Y(NO3)3(TBP)3] and hexane; the other contains variable proportions of acetonitrile and [Y(NO3)3(TBP)3] and small proportions of hexane. Intermolecular interaction parameters and excess Gibbs energies g

This contribution presents the results of a single crystal X-ray diffraction study of three ammine complexes of bivalent platinum
and palladium: [Pt(NH3)4](N03)2, [Pd(NH3)4](N03)2 and [Pd(NH3)4]F2H2O. The first two compounds are isostructural; metal atoms are located on inversion centers, all other atoms are in general
positions. A three-dimensional framework is built from planar-square complex cations and nitrate ions joined by N-H...O hydrogen
bonds. In [Pd(NH3)4]F2H2O, palladium atoms, as in the previous cases, are located on inversion centers, while oxygen atoms of water molecules are
on the two-fold symmetry axis. A network of strong N-H...F and O-H...F hydrogen bonds linking the cations, anions, and crystallization
water molecules is present in the structure. 相似文献

An XRD analysis is used to study the single crystal of [Pd(NH3)4][Rh(NH3)(NO2)5] double complex salt at T = 150(2) K. Crystallographic characteristics are as follows: a = 7.6458(5) ?, b = 9.8813(6) ?, c = 9.5788(7) ?, β = 109.469(2)°, V = 682.30(8) ?3, P21/m space group, Z = 2, d
x = 2.553 g/cm3. The geometry of the complex [Rh(NH3)(NO2)5]2− anion is described for the first time: Rh-N(NO2) distances are 2.020(4)–2.060(3) ?, Rh-N(NH3) 2.074(4) ?, N(NO2)-Rh-N(NH3) trans-angle is 178.8(2)°. 相似文献

Binary complex salts [Ru(NH3)5Cl][ReCl6] and [Ru(NH3)5Cl]2[ReCl6]Cl2 were synthesized and characterized. An X-ray diffraction analysis showed that they were isostructural with the previously
obtained isoformula salts [Rh(NH3)5Cl][OsCl6] and [Ir(NH3)5Cl]2[PtCl6]Cl2, respectively. Thermolysis of these compounds under hydrogen and helium was studied. According to X-ray phase analysis data,
bimetallic solid solutions Ru0.67Re0.33 and Ru0.50Re0.50 were the final products of thermolysis. Their unit cell parameters correspond to the characteristics of alloys with similar
compositions.

The zirconium nitrate complexes (NO2)[Zr(NO3)3(H2O)3]2(NO3)3 (1), Cs[Zr(NO3)5] ((2), (NH4)[Zr(NO3)5](HNO3) (3), and (NO2)0.23(NO)0.77[Zr(NO3)5] ((4) were prepared by crystallization from nitric acid solutions in the presence of H2SO4 or P2O5. The complexes were characterized by X-ray diffraction. The crystal structure of 1 consists of nitrate anions, nitronium cations, and [Zr(NO3)3(H2O)3]+ complex cations in which the ZrIV atom is coordinated by three water molecules and three bidentate nitrate groups. The coordination polyhedron of the ZrIV atom is a tricapped trigonal prism formed by nine oxygen atoms. The island structures of 2 and 3 contain [Zr(NO3)5]? anions and Cs+ or NH4 + cations, respectively. In addition, complex 3 contains HNO3 molecules. Complex 4 differs from (NO2)[Zr(NO3)5] in that three-fourth of the nitronium cations in 4 are replaced by nitrosonium cations NO+, resulting in a decrease in the unit cell parameters. In the [Zr(NO3)5]? anion involved in complexes 2–4, the ZrIV atom is coordinated by five bidentate nitrate groups and has an unusually high coordination number of 10. The coordination polyhedron is a bicapped square antiprism. 相似文献

A new 1,6-hexyldiamine heptaborate, [H3N(CH2)6NH3][B7O10(OH)3] (1), has been solvothermally synthesized and characterized by single-crystal X-ray diffraction, FTIR, elemental analysis, and thermogravimetric analysis. Compound 1 crystallizes in monoclinic system, space group P21/n with a=8.042(2) Å, b=20.004(4) Å, c=10.103(2) Å, and β=90.42(3)°. The anionic [B7O10(OH)3]n2n− layers are interlinked via hydrogen bonding to form a 3D supramolecular network containing large channels, in which the templated [H3N(CH2)6NH3]2+ cations are located. 相似文献

Ru3(CO)12 has been reacted with the compounds hex-1-en-3-yne [EtC≡CCH=CH2], 2-methyl-hex-1-en-3-yne [EtC≡CC(=CH2)CH3] and with 3(ethoxy-silyl)propyl isocyanate [(EtO)3Si(CH2)3NCO] and the compound tb [(EtO)3Si(CH2)3NHC(=O)OCH2C≡CCH2OC(=O)NH(CH2)3Si(OEt)3] in hydrocarbon solution. Some reactions in CH3OH/KOH solution (followed by acidification) have also been performed.
The main products of the reactions with ene-ynes are the clusters Ru3(CO)6(μ-CO)2L2 (L = C6H8, C7H10) and their demolition products, the “ferrole” Ru2(CO)6L2 complexes. One of the isomers of Ru3(CO)6(μ-CO)2L2, and Ru2(CO)6L2 (L = C7H10) have been reacted with vinyl-triethoxysilane [(EtO)3SiCH=CH2]: these reactions did not afford complexes containing new carbon–carbon bonds or triethoxy-silyl groups. Only polymerization
of vinyl-triethoxysilane occurred.
The reactions of Ru3(CO)12 with triethoxysilyl-propyl-isocyanate and tb (in the presence of Me3NO) lead to the same products, that is the isomeric complexes (μ-H)Ru3(CO)9[C=N(H)(CH2)3Si(OEt)3] with a “perpendicular” ligand (complex 3, as proposed on the basis of spectroscopic results) and (μ-H)Ru3(CO)9[HC=N(CH2)3Si(OEt)3] with a “parallel” ligand (complex 4, as confirmed by a X-ray analysis). The reaction pathways leading to these products are discussed. Complex 4 has been reacted with tetraethyl orthosilicate and the resulting material has been characterized. These reactions are part
of a study on the synthesis of inorganic-organometallic materials through sol–gel techniques.

Five complexes of type cis-[PtCl2(PR3)Q] (PR3 =PMe3, PMe2Ph, PEt3; Q = CH2 CHOCOCH3 or CH2=CHCH2OCOCH3) have been prepared. The crystal structure of cis-[PtCl2[PME2Ph)(CH2=CHOCOCH3)] is described. Crystals of cis-[PtCl2(PME2Ph)(CH2-CHOCOCH3)] are triclinic, with a 8.441(4), b 13.660(5), c 7.697(3) Å, a 101.61(3)°, β 111.85(3)° γ 95.22(3)°, pP1, Z = 2. The structure was determined from 2011 reflections I σ 3σ (I) and refined to R = 0.037. The CH3COO grouping is syn to the cis-PMe2Ph ligand, with bond lengths of PtCl (trans to P) 2.367(3), PtCl (trans to olefin) 2.314(3), PtP 2.264(2), and PtC of 2.147(12) and 2.168(11) Å. The complexes cis-[PtCl2- (PR3)Q] were studied by variable temperature 1H and 31P NMR spectroscopy. Spectra of the vinyl acetate complexes were temperature dependent as a result of rotation about the platinum—olefin bond. The rotation was “frozen out” at ca. 240 K; for cis-[PtCl2(PME2Ph)(CH2=CHOCOCH3] ΔG≠ (rotation) 15.0 ± 0.2 kcal mol-1. NMR parameters for the rotamers are reported. NMR studies of the interaction between chloro-bridged complexes of type [Pt2Cl2(PR3)2] (PR3 = P-N-Pr3 or PMe2Ph) and vinyl acetate shows that even at low temperatures (213 K) equilibrium favours the bridged complex and the proportion of trans-[PtCl2(PR3)CH2=CHOCOCH3)] is very small e.g. 2%. The allyl acetate complexes cis-[PtCl2(PR3)(CH2=CHCH2OCOCH3)] showed only one rotamer over the range 333–213 K. Reversible dissociation of cis-[PtCl2(PMe2Ph)- (CH2=CHCH2OCOCH3)] to [Pt2Cl4(PMe2Ph)2] + allyl acetate was studied at ambient temperature. At low temperatures e.g. 213–190 K addition of allyl acetate to a CDCl3 solution of [Pt2Cl2(P-n-Pr3)2] reversibly gave some olefin complex trans-[PtCl2(P-n-Pr3)(CH2=CHCH2OCOCH3)] and some O-bonded complex trans-[PtCl2(P-n-Pr3)(CH2=CHCH2OCOCH3)]. 相似文献

Thermogravimetric studies are reported for analytical precipitates of the types MPb[Co(NO2)6] and M2Pb[Co(NO2)6], where M represents the univalent cations NH+4, K+, Rb+, Cs+, and Tl+. Compounds of the latter series are consitently more stable to higher temperatures. For either series increasing the radius of M increases thermal stability. Decomposition to temperatures approaching 500°C involves some four separate processes. 相似文献
