The reactions of CdI2 with dimethylpyridines (Me2Py is C7H9N) afford complexes CdI2(2,3-Me2Py)2] (I), [CdI2(2,6-Me2Py) (II), and CdI2(3,5-Me2Py)2 (III). The structures of compounds I and II are determined. The crystals of complex I are orthorhombic, space group Pbca, a = 7.930(1) Å, b = 15.537(1) Å, c = 29.943(1) Å, V = 3689.1(5) Å3, ρcalcd = 2.090 g/cm3, Z = 8. The crystals of complex II are monoclinic, space group C2/c, a = 14.784(1), b = 11.991(1), c = 17.711(1) Å, β = 90.39(1)°, V = 1081.1(2) Å3, ρcalcd = 2.908 g/cm3, Z = 4. The structure of compound I is built of discrete neutral complexes [CdI2(2,3-Me2Py)2]. The Cd polyhedron is a distorted tetrahedron (Cd-I 2.289–2.295, Cd-N 2.708–2.734 Å, angles N(I)CdN(I) 103.1°-114.8°). Polymer chains [CdI2(2,6-Me2Py)]∞ extended along the direction [100] are observed due to the bridging iodine atoms in structure II. The Cd polyhedron is a trigonal bipyramid containing iodine atoms at the axial vertices (Cd-Iaks 3.040 Å) and two iodine atoms and the nitrogen atom of the Me2Py ligand in the equatorial plane Me2Py (Cd-Ieq 2.840 Å, Cd-N 2.309 Å). The compounds in the solid state are photoluminescent. 相似文献

The complex [CdI2(4-CNPy)2] (I) was obtained by a reaction of CdI2 with 4-cyanopyridine (4-CNPy, C6H4N2) and structurally characterized (CIF file CCDC no. 983377). The crystals of complex I are monoclinic, space group C2, a = 24.698(5) Å, b = 4.127(1) Å, c = 7.597(2) Å, β = 96.05(1)°, V = 770.0(3) Å3, ρcalcd = 2.477 g/cm3, Z = 2. In structure I, iodine atoms serve to unite complex molecules into the polymer chains [CdI2(4-CNPy)2]∞ along the direction [010]. The Cd(1) atom lying on a twofold axis has a slightly distorted octahedral environment made up of four bridging iodine atoms and two nitrogen atoms of two ligands 4-CNPy (Cd-Iav, 2.947(2) and Cd-N(1), 2.410(6) Å). Within each chain, cadmium atoms are spaced apart at 4.13 Å. Complex I exhibits photoluminescence. 相似文献

The reaction of the [B10H9O2C4H8]−, [B10H9OC4H8]−, and [B10H9OC5H10]− anions with negatively charged S-nucleophiles, such as SH−, SCN−, and S2O3
2−, resulted in the ring opening of the cyclic substituent and the formation of derivatives with the terminal thiol, thiocyanate,
and thiosulfate groups. The structures of the products were confirmed by the IR, mass, and 1H, 11B, and 13C NMR spectra. 相似文献

[СdI2(4-АmbaH)2] · H2O has been synthesized by the reaction between CdI2 and 4-aminomethylbenzoic acid (4-AmbaH) in an aqueous solution. According to X-ray diffraction data, a 4-AmbaH aromatic molecule crystallizes in the form of a zwitterion with protonation of the NH 3 + amino group and deprotonation of the carboxylate group, which is chelately coordinated to the Cd2+ ion. In addition to two iodine atoms, the Cd2+ atom located on the double crystallographic axis is coordinated to the chelate carboxylate O(1) and O(2) atoms of two crystallographically equivalent ligands 4-AmbaH. The octahedral geometry of the Cd2+ ion is strongly distorted due to the chelate addition of 4-AmbaH. The chelate coordination of COO–groups is confirmed by IR spectroscopy data. The complex has luminescent properties. 相似文献

A new method of synthesis of the B3H8− anion has been suggested. The method uses the reaction of some metal halides (CuCl, SnCl2, CrCl3, PbF2, PbCl2, PbBr2, and BiCl3) with sodium tetrahydroborate. It is characterized by high (up to quantitative) yields and simplicity of isolation of the
target products ((n-C4H9)4N)[B3H8] and Cs[B3H8]. 相似文献

Metal complex [AgL] (I) is synthesized by the reaction of AgNO3 with 3-(5-furyl-1,3,4-oxadiazol-2-yl)acrylic acid (HL, C9H6N2O4), and its crystal structure is determined (CIF file CCDC no. 1426528). The crystals are monoclinic, space group P21/n, a = 4.946(1), b = 20.084(1), c = 9.015(1) Å, β = 92.32(1)°, V = 894.482 Å3, ρcalcd = 2.442 g/cm3, Z = 4. In structure I, pairs of centrosymmetric silver atoms are bound by bidentate-bridging oxygen atoms of two anions L into dimeric blocks. The Ag–Ag distance in the dimer is 2.854(1) Å. The coordination sphere of Ag+ contains two oxygen atoms, one silver atom, and one nitrogen atom of the diazolyl fragment of the adjacent anion. The coordination polyhedron of Ag+ is a strongly distorted tetrahedron. The molecular packing of crystal I is built of infinite ribbons (AgL)n extended along the direction [001]. The photoluminescence spectrum of compound I contains intense bands about 550 nm corresponding to the green spectral range and less intense bands at 425 and 485 nm. 相似文献

The structures of the compounds (H2Phda)[SnF3]2 (I) and (H2Bipy)[SnF6] (II) have been determined. The main structural elements of I are anionic ([SnF3] n n? ) polymer chains and 1,4-phenylenediamine ([C6H4(NH3)2]2+) cations. The coordination polyhedron of Sn2+ is a trigonal bipyramid with a stereochemically active lone pair in the equatorial plane. The [SnF3E] n n? chains are crosslinked by phenylenediamine cations through N-H...F hydrogen bonds, resulting in supramolecular ensembles. The structure of II is built of separate [SnF6]2? complexes and 4,4′-bipyridinium ((C10H10N2)2+) cations linked by bifurcate N-H...F hydrogen bonds. These bonds combine the [SnF6]2? complexes into supramolecular layers alternating along the [100] direction with a period of 1/2a. 相似文献
