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

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. Crystals II are triclinic with unit cell parameters a = 8.7572(4) Å, b = 9.6934(6) Å, c = 18.665(1) Å; α = 79.374(2)°, β = 87.049(2)°, γ = 75.640(2)°; V = 1508.6(1) Å3; Z = 2, ρ = 1.259 g/cm3; space group
. 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
hydrogen bonds.

Two copper(I) complexes [Cu(Cin2bda)2]ClO4 (I) and [Cu(Ncin2bda)2]ClO4 (II) have been prepared by the reaction of the ligands N2,N2′-bis(3-phenylallylidene)biphenyl-2,2′-diamine (L1) and N2,N2′-bis[3-(2-nitrophenyl)allylidene]biphenyl-2,2′-diamine (L2) and copper(I) salt. These compounds were characterized by CHN analyses, 1H NMR, IR, and UV-Vis spectroscopy. The C=N stretching frequency in the copper(I) complexes shows a shift to a lower frequency
relative to the free ligand due to the coordination of the nitrogen atoms. The crystal and molecular structure of II was determined
by X-ray single-crystal crystallography. The coordination polyhedron about the copper(I) center in the complex is best described
as a distorted tetrahedron. A quasireversible redox behavior was observed for complexes I and II.

, where R = C4H9 (I) and R2 = (CH2)5 (II). The structures of the synthesized compounds solved by X-ray diffraction analysis are char-acterized by a complicated organization

and differential scanning calorimetry. The final product of the thermal transformations of the studied complexes is shown

A novel trinuclear manganese(II) complex, Mn3(C12H8N2)2(C10H11O5)6 (I), has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction. The crystal belongs to the monoclinic
system, space group P21/n, with cell parameters a = 12.1935(7), b = 19.0249(11), c = 18.0515(10)?, β = 105.0430(10)°, V = 4044.1(4)?3, Z = 2. Two of the three manganese atoms in the crystal structure are crystallographically equivalent and adopt N2O4 coordination mode, whereas the remaining manganese atom adopts O6 coordination mode, which forms a nearly regular octahedron. The experimental result of thermal analysis shows that complex
I remains stable below 300°C. 相似文献

The complex (η4-C4Me4)Co(CO)2I (I) reacted with excess SnCl2 in boiling THF to give, through replacement of the iodide ligand by the fragment SnCl3, the mononuclear complex (η4-C4Me4)Co(CO)2SnCl3 (II) containing the Co-Sn bond (2.459(1) ?). In a reaction of complex I with phenyltellurenyl halides PhTeI and PhTeBr, an analogous insertion into the cobalt-iodine bond yielded (η−C4Me4)Co(CO)2(TeI2Ph) (III) and (η4-C4Me4)Co(CO)2(TeBrIPh) (IV), respectively. This type of coordination of the aryltellurenyl halide fragment to the transition metal atom was observed
for the first time. X-ray diffraction analysis revealed a substantial shortening of the formally single Co-Sn and Co-Te bonds
in complexes II–IV compared to the sum of the covalent radii of the corresponding atoms.

The chemisorption properties of cadmium dibutyldithiocarbamate with respect to [AuCl4]− in 2M HCl solutions are studied. The heterogeneous reaction of gold(III) binding affords the heteropolynuclear compound ([NH{2(C4H9)2][Au{S2CN(C4H9)2}2][CdCl4])

(I). The molecular and crystal structures of compound I are determined from the X-ray diffraction data. Each of three ions is presented in the structure by two conformers. The irreversible
decomposition of some dibutyldithiocarbamate groups is observed during the chemisorption of gold(III), which noticeably decreases
the efficiency of gold binding with the sorbent studied and its sorption capacity. The study of the thermal properties of
compound I shows that gold(III) is reduced to the metal during thermolysis. 相似文献

According to X-ray diffraction, the crystal structure of I is composed of discrete centrosymmetric complex cations [CuL]2+ and iso-Bu2Ps2− anions. The CuN4 coordination unit is a square. The Cu...S distance (iso-Bu2PS2−) equal to 3.047 ? attests to possible S-coordination. Compounds I and II were studied by EPR. 相似文献
