2,2,3,3,5,5,6,6-Octa-p-tolyl-1,4-dioxa-2,3,5,6-tetra-germacyclo-hexane dichloro-methane disolvate.

ABSTRACT: The title compound, C(56)H(56)Ge(4)O(2)·2CH(2)Cl(2) or Tol(8)Ge(4)O(2)·2CH(2)Cl(2) (Tol = p-CH(3)C(6)H(4)), was obtained serendipitously during the attempted synthesis of a branched oligogermane from Tol(3)GeNMe(2) and PhGeH(3). The mol-ecule contains an inversion center in the middle of the Ge(4)O(2) ring which is in a chair conformation. The Ge-Ge bond distance is 2.4418 (5) Å and the Ge-O bond distances are 1.790 (2) and 1.785 (2) Å. The torsion angles within the Ge(4)O(2) ring are -56.7 (1) and 56.1 (1)° for the Ge-Ge-O-Ge angles and -43.9 (1)° for the O-Ge-Ge-O angle.

1,3-Bis(2,6-diisopropyl-phen-yl)imidazolidinium tetra-phenyl-borate dichloro-methane disolvate.

Project description:The title compound, C(27)H(39)N(2) (+)·C(24)H(20)B(-)·2CH(2)Cl(2), is the first reported imidazolidinium cation with the sterically demanding 2,6-diisopropyl-phenyl groups in the 1,3-positions. The crystal structure is stabilized by weak inter-molecular C-H??(arene) inter-actions. Due to the bulky nature of both the flanking 2,6-diisopropyl-phenyl substituents and the tetra-phenyl-borate counter-ion, anion inter-actions with the imidazolidinium H atom in the 2-position are not observed, also a first for this class of ortho-alkyl-substituted Arduengo-type carbene precursors.

2,3,5,6-Tetra-methoxy-piperazine-1,4-dicarbaldehyde.

Project description:The asymmetric unit of the title compound, C(10)H(18)N(2)O(6), contains two halves of two independent centrosymmetric mol-ecules with almost identical conformations. Weak inter-molecular C-H?O hydrogen bonds consolidate the crystal packing.

1-(2,6-Dichloro-benzo-yl)-3-(2,3,5,6-tetra-chloro-phen-yl)thio-urea trichloro-methane hemisolvate.

Project description:The title compound, C(14)H(6)Cl(6)N(2)OS·0.5CHCl(3), crystallizes with four 1-(2,6-dichloro-benzo-yl)-3-(2,3,5,6-tetra-chloro-phen-yl)thio-urea mol-ecules and two trichloro-methane mol-ecules in the asymmetric unit. The thiourea molecules exist in the solid state in their thione forms with typical thio-urea C-S and C-O bonds lengths, as well as shortened C-N bonds. The -NH-C(=S)-NH-C(=O)- plane is almost perpen-dicular to the benzene ring in each thiourea molecule. Intra-molecular N-H?O hydrogen bonds stabilize the mol-ecular conformation and inter-molecular N-H?S hydrogen bonds stabilize the packing arrangement.

Poly[[diaqua-(?(2)-1,4-dioxane-?O:O')(?(2)-2,3,5,6-tetra-fluoro-benzene-1,4-dicarboxyl-ato-?O:O)copper(II)] 1,4-dioxane disolvate dihydrate].

Project description:In the title complex, {[Cu(C(8)F(4)O(4))(C(4)H(8)O(2))(H(2)O)(2)]·2C(4)H(8)O(2)·2H(2)O}(n), the Cu(II) ion is six-coordinated by two oxygen donors from two trans 2,3,5,6-tetra-fluoro-1,4-dicarboxyl-ate (BDC-F(4)) ligands, two O atoms from two chair 1,4-dioxane ligands and two O atoms from two terminal water mol-ecules, adopting a distorted octa-hedral coordinated geometry. Each BDC-F(4) anion bridges two Cu(II) ions in a bis-monodentate fashion, forming a [Cu(BDC-F(4))](n) chain. These chains are further linked by bridging 1,4-dioxane ligands, generating a two-dimensional net with approximately recta-ngular grids of 11.253 × 7.654?Å. Such adjacent parallel layers are connected by O-H?O hydrogen bonds between guest water mol-ecules and the uncoordinated carboxyl-ate O atoms and coordinated water mol-ecules into the final three-dimensional supra-molecular network.

Crystal structure of (±)-[trans-cyclo-hexane-1,2-diylbis(aza-nedi-yl)]di-phospho-nium dibromide dichloro-methane disolvate.

Project description:The cation of the title solvated salt, C42H42N2P2 (2+)·2Br(-)·2CH2Cl2, lies on a crystallographic twofold rotation axis. The 1,2-di-amino-cyclo-hexane fragment has a chair conformation with two N atoms in a transoid conformation [N-C-C-N = 163.4 (2)°]. In the crystal, the cations are linked to the anions by N-H⋯Br and C-H⋯Br hydrogen bonds, forming a chain structure along the c axis. The di-chloro-methane mol-ecule takes part in the hydrogen-bond network through C-H⋯π and C-H⋯Br inter-actions.

trans-Dichloridotetra-pyrazine-ruthenium(II) dichloro-methane disolvate.

Project description:In the title compound, [RuCl(2)(C(4)H(4)N(2))(4)]·2CH(2)Cl(2), the Ru(II) atom occupies a position of 222 symmetry and the C atom of the solvent mol-ecule occupies a site with twofold symmetry. The Ru(II) atom has a slightly distorted octa-hedral geometry. The pyrazine rings are propeller-like and rotated 45.1 (1)° from the RuN(4) plane. In the crystal, the complex and solvent mol-ecules are bridged by weak C-H⋯N hydrogen bonds along the c axis. Weak inter-molecular C-H⋯Cl contacts link the complexes in the ab plane, forming a network.

2,3,5,6-Tetra-fluoro-1,4-bis-(trimethyl-sil-yl)benzene.

Project description:The asymmetric unit of the title compound, C(12)H(18)F(4)Si(2), contains two independent mol-ecules, both lying on inversion centers. The C(arene)-Si distances are significantly longer than in the analogous non-fluorinated compound. The packing of the mol-ecules results in a herringbone motif in the ac plane.

5,11,17,23-Tetra-bromo-25,26,27,28-tetra-kis(4-tolyl-sulfon-yloxy)-2,8,14,20-tetra-thia-calix[4]arene dichloro-methane solvate.

Project description:In the crystal structure of the title compound, C(52)H(36)Br(4)O(12)S(8)·CH(2)Cl(2), the thia-calix[4]arene unit adopts a 1,3-alternate conformation with an intra-molecular C-H?O hydrogen bond and four C-H?? inter-actions, with the four 4-MeC(6)H(4)SO(3) groups located alternately above and below the virtual plane (R) defined by the four bridging S atoms. The benzene ring of each 4-MeC(6)H(4)SO(3) unit is nearly perpendicular to one of the two neighboring phenol rings with inter-planar angles varying from 72.97?(13) to 78.70?(13)°, while the dihedral angles between the plane (R) and the phenol rings range from 83.04?(7) to 84.30?(9)°. In the supra-molecular structure, a solvent-bridged dimer composed of two main mol-ecules is formed by four inter-molecular C-H?O hydrogen bonds and locally creates an R(4) (4)(26) motif. Such dimers associate further into chains by inter-dimer C-Cl?O short contacts [Cl?O 3.182?(5)?Å]. Finally, these chains are linked into a two-dimensional network by a combination of inter-chain C-Br?O inter-actions [Br?O = 3.183?(3) and 2.966?(4)?Å] as well as C-H?O hydrogen bonds.

?-Oxalato-bis-[bis-(triphenyl-phosphine)copper(I)] dichloro-methane disolvate.

Project description:The dinuclear molecule of the title compound, [Cu(2)(C(2)O(4))(C(18)H(15)P)(4)]·2CH(2)Cl(2), lies across an inversion center with a strictly planar bridging oxalate ligand coordinating two Cu(I) ions via two pairs of O atoms. Two triphenyl-phosphine ligands also coordinate each symmetry-related Cu(I) ion, resulting in a distorted tetra-hedral geometry [O-Cu-O = 80.57?(5)° and P-Cu-P = 125.72?(2)°]. In the crystal, there are two dichloro-methane solvent mol-ecules for each dinuclear complex.

Chlorido(2,3,7,8,12,13,17,18-octa-ethyl-porphyrinato)iron(III) dichloro-methane sesquisolvate.

Project description:The title mol-ecule, [Fe(C(36)H(44)N(4))Cl]·1.5CH(2)Cl(2), is a high-spin square-pyramidal iron(III) porphyrinate with an average value for the equatorial Fe-N bond lengths of 2.065?(3)?Å and an axial Fe-Cl distance of 2.2430?(13)?Å. The iron cation is displaced by 0.518?(1)?Å from the 24-atom mean plane of the porphyrin ring. These values are typical for high-spin iron(III) porphyrinates.
