Dichloridobis(2-methoxydibenzo[c,e][1,2]oxaphosphorine-κP)platinum(II) trichloromethane solvate  [cached]
Tamás Holczbauer,György Keglevich,Andrea Kerényi,Mátyás Czugler
Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809006643
Abstract: The title compound, [PtCl2(C13H11O2P)2]·CHCl3, has a rare PtCl2 bridging of two dibenzooxaphosphorine ligands through the metal atom. The PtII ion is in a slightly distorted square-planar environment. The trichloromethane solvent molecule shows rotational disorder (major occupancy is 0.75) and is placed near to the inversion centre at (1/2, 1/2, 0) in channels parallel to the a axis. The solvent molecule is linked to the complex molecule via intermolecular bifurcated C—H...Cl and C—H...O hydrogen bonds. The crystal structure is further stabilized by π–π interactions involving the benzene rings, with a centroid–centroid distance of 3.658 (8) .

Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811049312
Abstract: In the title compound, [Re3(μ-H)3(C25H22P2)(CO)10]·CH2Cl2, the three Re atoms form a triangle bearing ten terminal carbonyl groups and three edge-bridging hydrides. The bis(diphenylphosphanyl)methane ligand bridges two Re atoms. Neglecting the Re—Re interactions, each Re atom is in a slightly distorted octahedral coordination environment. The dichloromethane solvent molecule is disordered over two sets of sites with fixed occupancies of 0.6 and 0.4.

Abstract: Titanium oxide sol was prepared by using inorganic titanium salt, and was used to photo-oxidize chloroform and chlorinated methane solution. Conductivity of solution was increased when chlorinated methane degraded under UV radiating. Addition of titanium oxide sol makes the degradation rate of chlorinated methane greater, and the conductivity will be changed. But when the added amount of the sol to solution is too much, the change rate of conductivity will be reduced for the reduced photo-oxidation of dichloromethane and trichloromethane. Suitable addition amount of the sol is benefit to photo-catalytic de-chlorination of dichloromethane and trichloromethane in solution.

Abstract: The title compound, C15H23NO2S, synthesized by N-methylation of cyclohexylamine sulfonamide with propyl iodide, is of interest as a precursor to biologically active sulfur-containing heterocyclic compounds. The cyclohexyl ring exists in the chair form and the dihedral angle between the ring plane of the benzene ring and that of the cyclohexyl ring is 50.13 (9)°.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808016577
Abstract: Cytenamide forms a 1:1 solvate with trifluoroacetic acid (systematic name: 5H-dibenzo[a,d]cycloheptatriene-5-carboxamide trifluoroacetic acid solvate), C16H13NO·C2HF3O2. The compound crystallizes with one molecule of cytenamide and one of trifluoroacetic acid in the asymmetric unit; these are linked by O—H...O and N—H...O hydrogen bonds to form an R22(8) motif. The trifluoromethyl group of the solvent molecule displays rotational disorder over two sites, with site-occupancy factors of 0.964 (4) and 0.036 (4).

Abstract: The title complex, {[Cu2(C10H8N2)(C25H22P2)2](BF4)2·2.5CH2Cl2}n, contains chains of CuI centres bridged alternately by two (diphenylphosphino)methane (dppm) and 4,4′-bipyridine (bpy) ligands. Each CuI atom is coordinated by one N atom of 4,4′-bipyridine (bpy) and two P atoms of two (diphenylphosphino)methane (dppm) ligand, and has a trigonal-planar coordination geometry. There is an inversion centre midway between each pair of adjacent Cu atoms. The distance of two CuI atoms separated by two (diphenylphosphino)methane bridging ligands is 3.732 (3) , and 4,4′-bipyridine 11.138 (5) .

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810029600
Abstract: In the title solvate, C30H39NO5·CH4O {systematic name: 21-acetoxy-18,21-dihydroxy-5,6,16,18-tetramethyl-10-phenyl-6,7-epoxy-[11]cytochalasa-13,19-dien-1-one methanol solvate}, the organic molecule exhibits the tetracyclic terpenoid skeleton of cytochalasin, consisting of fused five-, six-, three- and 11-membered rings. The five-membered ring adopts an envelope conformation, while the six-membered ring is in a boat conformation. The epoxy O atom on the six-membered ring is pointing away from the five-membered ring. An interstitial methanol solvent molecule is hydrogen bonded to the cytochalasin molecules and intermolecular O—H...O and N—H...O hydrogen bonds connect the molecules into infinite chains along the (overline{1}10) direction.
{1,8-Bis[2-(2-oxidobenzylideneamino)phenoxy]-3,6-dioxaoctane}nitratopraseodymium(III) trichloromethane solvate

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808021259
Abstract: In the title compound, [Pr(C32H30N2O6)(NO3)]·CHCl3, the PrIII ion is ten-coordinated by eight O atoms and two N atoms from the acyclic crown-type Schiff base ligand and the bidentate nitrate group. The coordination polyhedron around PrIII is a distorted bicapped square antiprism. The chloroform solvent molecule is not involved either in coordination to the PrIII center or in hydrogen bonding to the complex. The Pr—O(phenolate) bonds are significantly shorter than the Pr—O(ether) and Pr—O(nitrate) bonds, which suggests that the Pr—O(phenolate) bond is stronger than these other bonds. In the crystal structure, the acyclic crown-type Schiff base ligand wraps around the PrIII centre, forming a pseudo-ring.
