While seeking molecular precursors for ZnS films obtained by gas phase chemical deposition [1, 2] we synthesized mixed-ligand
compounds ZnL(ROCS2)2 [R = i-Pr. /-Bu; L = 2,2′-bipyridyl (2,2′-Bipy), 1,10-phenanthroline (Phen)] [3]. The volatile complex Zn(2,2′-Bipy)(i-PrOCS2)2 was used as a precursor to obtain electroluminescent ZnS:Mn films [4]. According to XRD data, the compound Zn(Phen)(i-BuOCS2)2 is monomeric. The c.n. of zinc is six. The Phen and 1-B11OCS2 ions behave as cyclic bidentate ligands [3, 5]. It was assumed that other mixed-ligand complexes with Phen and 2,2′-Bipy
have an analogous structure [3]. Here we report on the structure of the known mixed-ligand complex of zinc(II) ethylxanthate
with 2,2′-bipyridyl [6, 7]. It was found that the behavior of alkylxanthate ligands in mixed-ligand complexes of zinc(II)
is more complex.

A new coordination polymer [Pb(2,2′-Bipy)(NO3)2(H2O)] n has been successfully synthesized and characterized (where 2,2′-Bipy = 2,2′-bipyridine). The crystal structure of the polymer was determined by single-crystal X-ray diffraction, crystallizing in the monoclinic crystal system, space group P21/n with unit cell parameters: a = 7.1673(5), b = 9.8706(6), c = 19.1825(12) Å; β = 90.0780(10)°; V = 1357.08(15) Å3, and Z = 16. The Pb atom was six-coordinated with N(1) and N(2) from 2,2′-Bipy, O(2), O(3), and O(6) in nitrate; O(1) from coordinated water, forming a slightly distorted octahedral geometry. The structure units aggregate together to give birth to the infinite 1D chains via bridged nitrate, and 2D networks and three-dimensional frameworks were obtained through hydrogen bonding and π-π-stacking interaction among aromatic rings, respectively. 相似文献

The structures of the mixed-ligand complexes Zn(4,4-Bipy){(n-C3H7)2NCS2}2 (I) and Zn2(4,4-Bipy){(n-C3H7)2NCS2}4 (II) were determined by single crystal X-ray diffractometry (CAD-4 diffractometer, MoK radiation, 2479 and 1616 Fhkl, R = 0.0550 and 0.0523). The crystals are monoclinic with cell parameters a = 16.560(2), b = 11.423(1), c = 15.319(2) , = 94.27(1)°, V = 2889.8(6) 3, Z = 4, space group P21/c (for I) and a = 8.515(1), b = 10.965(1), c = 27.816(3) , = 95.860(1)°, V = 2583.5(5) 3, Z = 2, space group P21/n (for II). The structure of I is composed of discrete mononuclear molecules; the structure of II consists of discrete centrosymmetric binuclear molecules. The coordination polyhedra of the Zn atoms (c.n. 5) are formed by four S atoms of the two cyclic bidentate dithiocarbamate ligands and the N atom of the 4,4-Bipy ligand, which is monodentate in I and bridging bidentate in II. Molecular packings and interactions in the structures are considered. 相似文献

Heteroligand complexes Tm(L)(iso-Bu2PS2)2(NO3) (L = 2,2′-Bipy (II), Phen (III)) are synthesized. According to the X-ray phase analysis data, complex III is isostructural to mononuclear compound [Dy(Phen)(iso-Bu2PS2)2(NO3)] including, according to the X-ray diffraction data, a coordination polyhedron DyN2O2S4 (distorted dodecahedron). Single crystals of compounds [Ln(2,2′-Bipy)(iso-Bu2PS2)2(NO3)] · C6H6 (Ln = Tm (IV), Tb (V)) are obtained. An X-ray diffraction analysis shows that the crystal structures of these isostructural compounds are formed by molecules of mononuclear complexes [Ln(2,2′-Bipy)(iso-Bu2PS2)2(NO3) and uncoordinated C6H6 molecules. In complexes IV and V, the ligands [Ln(2,2′-Bipy)(iso-Bu2PS 2 ? , and NO 3 ? are bidentate-cyclic. The coordination polyhedron LnN2O2S4 is a distorted dodecahedron. Complexes II and III possess photoluminescence in the visible spectral range (λmax = 478 and 477 nm, respectively). 相似文献

A novel complex [Zn(FcCOO)2(2,2′-bipy)(H2O)]2·H2O (Fc = (η5-C5H5)Fe(η5-C5H4), 2,2′-bipy = 2,2′-bipyridine) has been synthesized and characterized by elemental analysis, IR and X-ray diffraction. It crystallizes in monoclinic system, space group P21/c with a = 6.8187(4), b = 21.7155(13), c = 19.7411(12) (A), α = 90, β = 97.7420(10), γ = 90°, C64H58Fe4Zn2N4O11, Mr = 1413.28, V = 2896.4(3) (A)3, Dc = 1.620 g/cm3, Z = 2, F(000) = 1444, μ(MoKα) = 1.857 mm-1, R = 0.0523 and wR = 0.0982 for 3219 observed reflections (I > 2σ(I)). Structural analysis shows that the zinc atom is coordinated with three oxygen atoms from two ferrocenemonocarboxylates and one water molecule together with two nitrogen atoms from 2,2′-bipyridine, giving a distorted square-pyramidal coordination geometry. The complex molecules are linked to form an infinite one-dimensional chain by both intermolecular hydrogen bonds and π-π stacking interactions of the bipyridine rings. 相似文献

Five compounds of the composition Ln(2,2′-Bipy)(C4H8NCS2)3 · 0.5CH2Cl2 (Ln = Sm (I), Eu (II), Tb (III), Dy (IV), and Tm (V); 2,2′-Bipy = 2,2′-bipyridine) are synthesized. According to the X-ray diffraction data (CIF file CCDC 986259), the crystal structure of compound I consists of molecules of the mononuclear complex [Sm(2,2′-Bipy)(C4H8NCS2)3] and solvate molecules CH2Cl2 (2 : 1). The coordination polyhedron N2S6 of the Sm atom is a distorted tetragonal antiprism. The X-ray diffraction analysis shows that compounds I–V are isostructural. The magnetic properties of compounds I–V are analyzed in the temperature range from 2 to 300 K. At 300 K compounds I and III are photoluminescent in the visible spectral range. The photoluminescence intensity of compound I considerably exceeds that of complex III. 相似文献

Two new Cd(II) coordination polymers, [Cd(C4H6N2)2(C4H2O4)(H2O)2] n (1) (where C4H6N2?=?2-methylimidazole, C4H2O4?=?fumarate), and [Cd(C4H6N2)(H2O)(C4H4O4)] n ?·?nH2O (2), (where C4H4O4?=?succinates), have been prepared and structurally characterized by single crystal X-ray diffraction. Complex 1 crystallizes in the triclinic space group P 1 in a one-dimensional chain structure, in which carboxy is monodentate; a three-dimensional supermolecular network structure was formed through hydrogen bonding. In complex 2, the coordination geometry of the Cd atoms is a pentagonal bipyramid, and a two-dimensional sheet is formed though carboxyl group bridging. In 1 and 2, IR spectra indicate the presence of bridging carboxyl groups, confirmed by structure analyses. 相似文献

Two oxo-vanadium(IV) complexes, [VO(C2O4)(2,2′-bipy)(H2O)]·C2H5OH(1) and VO(C2O4)(phen)(H2O) (2), where 2,2′-bipy=2,2′-bipyridyl, phen=1,10-phenanthroline, were synthesized as potential functional models of vanadium haloperoxidases(VHPOs) in mixed solvent of ethanol and water at room temperature. The complexes were characterized by elemental analysis, infrared(IR), UV-Vis and X-ray crystallography. Structural analyses showed that vanadium atom was coordinated by a terminal oxygen, one oxygen atom from coordinated water, two oxygen atoms from the carboxylate group of oxalic acid, and two nitrogen atoms(N1 and N2) from 2,2′-bipy/phen. Central vanadium atoms in complexes 1 and 2 were both in a distorted-octahedral environment, and some intermolecular hydrogen bonding linkages were also observed in each complex. Bromination reaction activity of the two complexes was evaluated with phenol red as organic substrate in the presence of H2O2, Br- and phosphate buffer, indicating that they can be considered as a potential functional model of VHPO. In addition, thermal analysis was also performed and discussed in detail. 相似文献

The crystal structure of guanidinlum pentamolybdobis(n-ainylphcsphonate), which contains the longest carbon chain hitherto known, was determined by single-crystal X-ray diffraction analysis. It belongs to monoclinic, space group C2/c, Z = 4, 0=18.857(2), b=12.170(1), c=18. 294(2) A .β=102.73 (2), V=4095. 2A3.u= 140. 34 cm-1. The intensity data were collected on an Enraf-Nonius CAD4 diffractometer with MoKa radiation. The positions of all molybdenum and phosphorus atoms were determined by the direct method. The other non-hydrogen atoms were revealed by difference Fourier synthesis. The structure was refined by full-matrix least-squares procedure to a final R value of 0. 068. The structure of the anion is similar to [(CH2P)2Mo5O21]4-, [(NH3C2H4P)2Mo6O21]2-, [(n-C3H7As)2Mo5O21]--, and [(C3H5As)2Mo6O21]4-. It consists of a ring of five distorted MoO, octahedra joined by edge-sharing, except for one pair which is joined by corner- sharing.

The i.r. spectra of (2–5) display typical bands of monodentate N-bonded cyanate groups, whereas the n.m.r. data of (4) are consistent with the presence of a bridging 2,2-bipyridine ligand. Complex (4) decomposes slowly in acetone. One of the products formed, [Pd(H2CCOMe)Cl(2,2-bipy)](6), was characterized by X-ray diffraction.

(where Pht is a doubly deprotonated phthalic acid residue and 4,4-Bipy is 4,4-bipyridine) was synthesized and studied by X-ray diffraction. It was shown that both ligands perform a bridging function and unite the Zn atoms into a two-dimensional network with a periodicity of 11.302(2) Å (with 4,4-Bipy as the bridge) or 7.627(2) Å (with Pht as the bridge). The coordination polyhedron of Zn is a distorted octahedron with C

Thermal degradation of a mixed-valence oxalate based molecular material {N(n-C4H9)4[FeIIFeIII(C2O4)3]}?? was investigated by thermogravimetric (TG) analysis. Considering the mass loss at each step of TG profile, possible step-wise thermal degradation reaction pathways of the precursor material are proposed which indicate the formation of hematite and magnetite as the solid end product of the degradation reaction. The IR spectroscopy and powder X-ray diffraction (XRD) studies of the thermally degraded samples supplement the proposed reaction pathways. 相似文献

Abstract The trietheylaluminum based ferrocenylalane (η5?C5H5)Fe[η5?C5H4Al2(C2H5)4Cl] was prepared from the reaction of triethylaluminum with chloromercuriferrocene in toluene and characterized by single crystal X-ray diffraction. The compound crystallizes in the triclinic space group P 1 with unit cell dimensions a = 9.353(3) Å, b = 10.281(7) Å, c = 11.599(9) Å, α = 79.64(7)°, β = 69.41(6)°, γ = 84.33(4)°, and Z = 2 for Dc = 1.27 g cm?3. Full-matrix least-squares refinement has led to a final R factor of 0.068 based on 1866 independent observed reflections. The two diethylaluminum units are bridged by a chlorine atom and one carbon atom of a cyclopentadienyl group, thus forming an Al-Cl-Al-C ring. The four-membered ring is planar to within 0.02 Å. The Al-Cl distances are 2.404(4) Å and 2.266(5) Å. The Al-Cl-Al angle is 78.9(1)° while the Al-C-Al angle is 91.3(4)°. No significant aluminum-iron interaction is observed (Al… Fe = 3.137(4) Å). 相似文献
