Michael Bolte Jörn Plackmeyer

In the paper by Bolte [Acta Cryst. (2006), E62, m1609-m1610], the chemical name in the title and the chemical diagram are incorrect. The correct title is {5-[4'-(2,2,5,5-Tetramethyl-3-pyrroline-1-oxyl-3-carbonyloxy)biphenyl-4-ylethynyl]-2,3,7,8,12,13,17,18-octaethylporphyrinato}copper(II) benzene solvate' and the correct diagram is given below.

trans-Dichloridobis(triphenylphosphane-κP)palladium(II) benzene hemisolvate (2012)

Frank Meyer-Wegner Hans-Wolfram Lerner Tanja Sinke Michael Bolte

The title complex, [PdCl2(C18H15P)2]·0.5C6H6, has the PdII ion in a square-planar coordination mode (r.m.s. deviation for Pd, P and Cl atoms = 0.024 Å) with the PPh3 and Cl ligands mutually trans. The benzene solvent molecule is located about a crystallographic inversion centre. The title complex is isostructural with trans-dichloridobis(triphenylphosphane)palladium(II) 1,4-dichlorobenzene sesquisolvate [Kitano et al. (1983 [triangle]). Acta Cryst. C39, 1015–1017].

Hannes Vitze Hans-Wolfram Lerner Michael Bolte

The crystal structure of the title compound, hexa-μ2-bromido-μ4-oxido-tetrakis[(diethyl ether)magnesium], [Mg4Br6O(C4H10O)4], determined from data measured at 173 K, differs from the previously known structure of diethyl ether magnesium oxybromide, which was determined from room-temperature data [Stucky & Rundle (1964 [triangle]). J. Am. Chem. Soc. 86, 4821–4825]. The title compound crystallizes in the tetragonal space group I An external file that holds a picture, illustration, etc. Object name is e-67-m1614-efi7.jpg, whereas the previously known structure crystallizes in a different tetragonal space group, namely P An external file that holds a picture, illustration, etc. Object name is e-67-m1614-efi7.jpg21 c. Both molecules have crystallographic An external file that holds a picture, illustration, etc. Object name is e-67-m1614-efi7.jpg symmetry and show almost identical geometric parameters for the Mg, Br and O atoms. The crystal of the title compound turned out to be a merohedral twin emulating a structure with apparent Laue symmetry 4/mmm, whereas the correct Laue group is just 4/m. The fractional contribution of the minor twin component converged to 0.462 (1).

Tetrakis(diethyl ether)tetra-μ4-oxido-octakis(pentafluorophenyl)octazinc (2011)

Daniel Franz Hans-Wolfram Lerner Michael Bolte

Mol-ecules of the title compound, [Zn(8)(C(6)F(5))(8)O(4)(C(4)H(10)O)(4)], are located on a special position of site symmetry [Formula: see text]. As a result, there is just one quarter-mol-ecule in the asymmetric unit. The title compound features a Zn(4)O(4) cube. Each Zn atom in the cube carries a pentafluorophenyl substituent. Each O atom is bonded to a further Zn atom, which is connected to a pentafluorophenyl substituent and the O atom of a diethyl ether mol-ecule. All ether C atoms are disordered over two sets of sites with a site occupation factor of 0.51 (2) for the major occupied site.

Tetrabutylammonium tris(methylsulfanylmethyl)phenylborate (2010)

Jan Tillmann Hans-Wolfram Lerner Michael Bolte

In the title molecular salt, C16H36N+·C12H20BS3-, three of the four n-butyl chains show a trans conformation, whereas the fourth has the C—C—C—C torsion angle in a gauche conformation [-77.8 (5)°]. In the crystal, molecules are packed in layers parallel to the (101) plane.

Tetraacetonitrilelithium tetraisothiocyanatoborate (2013)

Jens Michael Breunig Ulrich Wietelmann Hans-Wolfram Lerner Michael Bolte

The crystal structure of the title salt, [Li(CH3CN)4][B(NCS)4], is composed of discrete cations and anions. Both the Li and B atoms show a tetrahedral coordination by four equal ligands. The acetonitrile and isothiocyanate ligands are linear. The bond angles at the B atom are close to the ideal tetrahedral value [108.92 (18)–109.94 (16)°], but the bond angles at the Li atom show larger deviations [106.15 (17)–113.70 (17)°].

Tetrakis(μ(3)-9-oxa-10-boraanthracen-10-olato)tetrakis[(diethyl ether)lithium] (2011)

Daniel Franz Hans-Wolfram Lerner Dominik Büttner Michael Bolte

The title compound, [Li4O4(C12H8BO)4(C4H10O)4], features a Li4O4 cube. Each Li atom in the cube is additionally coordinated by a diethyl ether molecule and each O atom in the cube carries a 9-oxa-10-boraanthracene residue. The crystal studied was a non-merohedral twin [twin law (-1 0 0 / 0 0 1 / 0 1 0); the contribution of the major twin component refined to 0.553 (3)] emulating apparent tetragonal symmetry, whereas the actual crystal system is just orthorhombic.

Tetra-my3-tert-butanolato-tetrathallium(I) (2010)

Florian Blasberg Hans-Wolfram Lerner Michael Bolte

The title compound, [Tl4(C4H9O)4], featuring a (Tl—O)4 cube, crystallizes with a quarter-molecule (located on a special position of site symmetry An external file that holds a picture, illustration, etc. Object name is e-66-m1621-efi1.jpg..) and a half-molecule (located on a special position of site symmetry 23.) in the asymmetric unit. The Tl—O bond distances range from 2.463 (12) to 2.506 (12) Å. All O—Tl—O bond angles are smaller than 90° whereas the Tl—O—Tl angles are wider than a rectangular angle.

Synthesis and Crystal Structure of 1-(3-fluorophenyl)-3-(3,4,5-trimethoxybenzoyl)thiourea (2011)

Aamer Saeed Uzma Shaheen Michael Bolte

The title thiourea was synthesized by reaction of 3,4,5-trimethoxybenzoyl isothiocyante with 3-fluoroaniline. The 3,4,5-trimethoxybenzoyl isothiocyante was produced in situ by reaction of 3,4,5-trimethoxybenzoyl chloride with ammonium thiocyanate in dry acetonitrile. The structure was confirmed by the spectroscopic, elemental analysis and single crystal X-ray diffraction data. It crystallizes in the monoclinic space group P21/c with unit cell dimensions a = 13.0966(9), b = 16.6460(13), c = 7.8448(5), β = 106.721(5)°, V 1637.9(2) Å³, Z = 4.
