Tetraphenylantimony nitrite was synthesized by reacting pentaphenylantimony with triphenylantimony dinitrite at a molar ratio of 1 : 1 in toluene, and its structure was determined using X-ray diffraction analysis. The Sb atom is coordinated to the oxygen atom of the axial nitrite group to form a trigonal bipyramid. The Sb–C(Ph)eq distances vary within the 2.103–2.111(3) Å range, and the S–O(1) and Sb–C(41) bond lengths are equal to 2.386(3) and 2.156(3) Å, respectively. The Sb...N distance and the axial C(41)SbO(1) angle are equal to 3.133(4) Å and 174.7(1)°, respectively. 相似文献

Tetraphenylantimony N,N-dimethyldithiocarbamate (I) and tetra-p-tolylantimony N,N-dimethyldithiocarbamate (II) were synthesized via the reaction of tetraarylantimony chloride Ar4SbCl (Ar = C6H5 or C6H4Me-4) with sodium N,N-dimethyldithiocarbamate in water. According to the X-ray diffraction data, the tetraarylantimony N,N-dimethyldithiocarbamate molecules have a distorted octahedral configuration. The Sb–S bond lengths are equal to 2.7158(5) Å, 2.7440(5) Å and 2.761(2) Å, 2.8002(2) Å for I and II, respectively. 相似文献

The crystal structure of boron difluoride 3-phenylthiopentane-2,4-dionate was determined. The relationship between the structure and luminescent properties is traced in the series of boron difluoride acetyl acetonates (acetyl acetonate, phenylacetyl acetonate, and phenylthioacetyl acetonate). The presence of the π stacking interactions in boron difluoride phenylthioacetyl acetonate crystals leads to increased intensity and bathochromic shift of the fluorescence band. 相似文献

The crystal structure of the [Tb(BTFA)2(NO3)(TPPO)2] complex (TPPO is triphenylphosphine oxide, BTFA is benzoyltrifluoracetone), which exhibits strong triboluminescence, has been established by X-ray crystallography. The crystals are triclinic: a = 11.668(3) Å, b = 11.700(3) Å, c = 12.512(3) Å, α = 65.161(4°), β = 79.120(4)°, γ = 61.860(4)°, space group P1, Z = 1. The central terbium(III) atom coordinates two oxygen atoms from two triphenylphosphine oxide molecules (Tb-O, 2.264(3) and 2.273(3) Å), two oxygen atoms from the nitrate group (Tb-O, 2.460(3) and 2.476(3) Å), and four oxygen atoms from two benzoyltrifluoroacetonate groups (Tb-O, 2.329(3), 2.399(3), 2.351(3), and 2.367(3) Å). The coordination polyhedron of the Tb(III) atom is a distorted dodecahedron. The photoluminescence and triboluminescence spectra of the [Tb(BTFA)2(NO3)(TPPO)2] complex are identical and caused by the f-f luminescence of Tb3+. 相似文献

The crystal structure of (C2H5)4N)2TeCl6 was determined by X-ray diffraction (a = 14.130(2) Å, b = 14.547(2)Å, c = 13.296(2)Å, β= 90.356(3)°; space group C2/c, Z = 4, ρ(calcd) = 1.387 g/cm3). The crystal structure is composed of the [TeCl6]2? anions and tetraethylammonium cations ((C2H5)4N)+. The electronic and geometric aspects that determine the spectral luminescence and thermochromic properties of the complex are discussed. 相似文献

The crystal structure of europium cinnamate of the composition [Eu(Cin)3] n (Cin is cinnamic acid anion C9H7O 2 ? ) was determined by X-ray crystallography (a = 22.626(1) Å, c = 7.7330(7) Å, space group R3/c, Z = 3, ρcalc = 1.448 g/cm3). The coordination polyhedron of Eu atoms is a distorted trigonal prism with three centered square faces. The structure is built of infinite polymeric chains [Eu(Cin)3] n running along the c axis and linked by van der Waals and π stacking interactions. Luminescent characteristics of the compound were determined. 相似文献

The atomic structure of antimony(III) bromide crystals with anilinium was determined by X-ray diffraction analysis of (C6H5NH3)2SbBr5 (a = 19.704(3) Å, b = 7.914(1) Å, c = 25.556(4) Å; space group Pbca, Z = 8, ρcalc = 2.365 g/cm3). The crystal structure consists of infinite chains of [SbBr5]2? complex anions formed by sharing six vertices and the anilinium (C6H5NH3)+ cations, through which the chains are linked in layers by N-H...Br hydrogen bonds. The geometrical aspects that determine the luminescent spectral properties of the complex are discussed. 相似文献
