Acetonitrile-[2-({bis[2,4,6-tris-(trifluorido-meth-yl)phen-yl]phosphan-yloxy}meth-yl)pyridine]-meth-ylpalladium(II) hexa-fluoro-anti-monate dichloro-methane hemisolvate.

ABSTRACT: In the title compound, [Pd(CH(3))(C(24)H(10)F(18)NOP)(CH(3)CN)][SbF(6)]·0.5CH(2)Cl(2), the Pd(II) atom has a distorted square-planar environment being coordinated by an acetonitrile N atom [Pd-N = 2.079 (3) Å], a methyl C atom [Pd-C = 2.047 (4) Å] and the bidentate ligand 2-({[2,4,6-tris-(trifluoro-meth-yl)phen-yl]phosphan-yloxy}meth-yl)pyridine (L). In L, the short distance of 3.621 (3) Å between the centroids of pyridine and benzene rings indicates the presence of a π-π inter-action. The crystal packing exhibits weak inter-molecular C-H⋯F contacts. The solvent mol-ecule has been treated as disordered between two positions of equal occupancy related by an inversion center.

Trichlorido[(meth-yl{2-[meth-yl(2-pyridyl-meth-yl)amino]eth-yl}amino)acetonitrile]iron(III) methanol hemisolvate.

Project description:The title compound, [FeCl(3)(C(12)H(18)N(4))]·0.5CH(3)OH, contains an Fe(III) ion in a distorted octa-hedral coordination environment. The neutral N,N',N''-tridentate ligand adopts a fac coordination mode, and chloride ligands lie trans to each of the three coordinated N atoms. In the crystal, the complexes form columns extending parallel to the approximate local threefold axes of the FeN(3)Cl(3) octa-hedra, and the columns are arranged so that the uncoordinated nitrile groups align in an anti-parallel manner and the pyridyl rings form offset face-to-face arrangements [inter-planar separations = 2.95?(1) and 3.11?(1)?Å; centroid-centroid distances = 5.31?(1) and 4.92?(1)?Å]. The methanol solvent mol-ecule is disordered about a twofold rotation axis.

Project description:In the title compound, C(24)H(39)N(3)O(3), the H atoms of the methyl groups are disordered over two positions, with site-occupation factors fixed at 0.5. The three morpholino groups are arranged in an asymmetrical fashion with respect to the anchoring mesitylene ring and adopt chair conformations. Inter-molecular C-H?? inter-actions link the mol-ecules into a one-dimensional chain structure.

Tris(1H-benzimidazol-3-ium-2-ylmeth-yl)amine tris-(2,4,6-trinitro-phenolate) acetonitrile disolvate.

Project description:In the cation of the title salt, C(24)H(24)N(7) (3+)·3C(6)H(2)N(3)O(7) (-)·2C(2)H(3)N, the three benzimidazolium ring systems are oriented to each other at dihedral angles of 10.42?(7), 23.98?(7) and 22.17?(7)°. In the crystal, the cation links to the adjacent picrate anions via N-H?O hydrogen bonds; one of independent acetonitrile solvent mol-ecules is also linked to the cation via an N-H?N hydrogen bond.

1,3,5-Tris(4-meth-oxy-phen-yl)-1,3,5-triazinane-2,4,6-trione.

Project description:The complete mol-ecule of the title compound, C24H21N3O6, is generated by the application of threefold rotation symmetry about an axis perpendicular to the central ring. The mol-ecule exhibits a propeller-like shape. The dihedral angle between each benzene ring and the heterocyclic ring is 74.0?(1)°. The mol-ecules pack with no specific inter-molecular inter-actions between them. The SQUEEZE procedure in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155] was used to model disordered solvent mol-ecules, presumed to be acetone; the calculated unit-cell data do not take into account the presence of these.

Project description:In the title compound, C36H24Br3N3O6·C7H8, the toluene solvent mol-ecule is associated with the receptor mol-ecule via C-H?? bonding. The planes of the phthalimido groups are inclined at 77.0?(1), 63.0?(1) and 77.8?(1)° with respect to the benzene ring. The mol-ecular conformation is stabilized by C-H?O and C-H?Br hydrogen bonds. The crystal structure features non-classical hydrogen bonds of the C-H?N, C-H?O and C-H?Br type, leading to a three-dimensional cross-linking of molecules. The pattern of non-covalent inter-molecular bonding is completed by O?Br halogen bonds [3.306?(3)?Å], which link the receptor mol-ecules into infinite strands extending along the a-axis direction.
