4,4'-Bis(dimethyl-amino)benzhydryl phenyl sulfone.

ABSTRACT: In the title compound, C(23)H(26)N(2)O(2)S, the sulfur-bound phenyl group is aligned approximately parallel to one of the two rings of the benzhydryl group, making a dihedral angle of 1.15 (9)°. The other forms a dihedral angle of 59.20 (9)° with the phenyl group bound to the S atom. In the crystal, mol-ecules are linked into strands along [100] by weak C-H⋯O contacts. Weak C-H⋯π inter-actions are also observed.

Benzhydryl phenyl sulfone.

Project description:In the title compound, C(19)H(16)O(2)S, the sulfur-bound phenyl group is approximately parallel to one of the two phenyl rings of the benzhydryl group, making a dihedral angle of 12.53?(10)°, and forms a dihedral angle of 41.25?(9)° with the other phenyl ring.

4,4'-Dimethyl-1,1'-(p-phenyl-enedimethyl-ene)dipyridinium bis-[7,7,8,8-tetra-cyano-quinodimethanide(1-)].

Project description:In the title salt, C(20)H(22)N(2) (2+)·2C(12)H(4)N(4) (-), the cations and anions stack along the b axis into segregated columns. In the cation, which has a crystallographically imposed centre of symmetry, the dihedral angle between the benzene and pyridine rings is 89.14?(4)°. Centrosymmetrically related anions form dimers by ?-? stacking inter-actions, with centroid-centroid separations of 3.874?(4)?Å. The crystal packing is stabilized by inter-columnar C-H?N hydrogen bonds.

1,1'-Dimethyl-4,4'-bipyridinium bis-(triiodide).

Project description:In the title compound, C(12)H(14)N(2) (2+)·2I(3) (-), the 1,1'-dimethyl-4,4'-bipyridinium (DMBP) dication is charge balanced by two triiodide ions. The DMBP dication is planar within 0.010 (5) Å. The asymmetric unit contains only half of the dication, the other half being generated by an inversion center. Weak C-H⋯I inter-actions link the ions into sheets parallel to (121).

Bis{?-4,4'-dibromo-2,2'-[o-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato}bis-[chloridomanganese(III)] N,N-dimethyl-formamide disolvate.

Project description:The asymmetric unit of the title compound, [Mn(2)(C(20)H(12)Br(2)N(2)O(2))(2)Cl(2)]·2C(3)H(7)NO, contains one half of a centrosymmetric dinuclear Mn(III) complex and an N,N-dimethyl-formamide solvent mol-ecule. In the complex, the two Mn(III) ions are bridged by two O atoms from two symmetry-related N,N'-bis-(5-bromo-salicyl-idene)-1,2-diimino-benzene dianionic ligands with the longer Mn-O distance of 2.703?(3)?Å, thus each Mn ion is six-coordinated by two N and three O atoms from the two dianionic ligands and one capping Cl atom in a distorted octa-hedral environment. The crystal structure displays inter-molecular ?-? inter-actions between adjacent benzene rings, with a shortest centroid-centroid distance of 3.673?(2)?Å, and inter-molecular C-H?O, C-H? Cl and C-H? Br hydrogen bonds.

4-(Dimethyl-amino)phenyl phenyl ketone.

Project description:In the crystal structure of the title compound, C(15)H(15)NO, the two benzene rings are twisted from each other by a dihedral angle of 47.97 (4)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯π inter-actions, and π-π inter-actions with a centroid-centroid distance of 3.8493 (5) Å are observed.

Poly[diaqua-[μ6-4,4'-(1,4-phenyl-ene)bis-(2,6-dimethyl-pyridine-3,5-dicarboxyl-ato)]dilead(II)].

Project description:The asymmetric unit of the title Pb-based coordination polymer, [Pb2(C24H16N2O8)(H2O)2] n , consists of one Pb(II) cation, half of a 4,4'-(1,4-phenyl-ene)bis-(2,6-dimethyl-pyridine-3,5-di-carb-oxyl-ate (L (4-)) ligand and one coordinating water mol-ecule. The centers of the benzene ring of the ligand and the four-membered Pb/O/Pb/O ring are located on centers of inversion. The Pb(II) ion is coordinated in form of a distorted polyhedron by seven O atoms from four separate L (4-) ligands and by one water O atom. The PbO7 polyhedra share O atoms, forming infinite zigzag [PbO4(H2O)] n chains along [100] that are bridged by L (4-) ligands, forming a two-dimensional coordination network parallel to (001). O-H⋯O hydrogen bonds involving the water mol-ecule are observed.

4,4'-[4,4'-Sulfonyl-bis-(p-phenyl-ene-oxy)]dibutanoic acid.

Project description:In the title compound, C(20)H(22)O(8)S, the dihedral angle between the two benzene rings is 81.6?(3)°. The benzene-connected portions of the alk-oxy substituents are almost coplanar with their respective rings [C-C-O-C torsion angles of 174.77?(17) and -178.5?(4)°]. One of the butanoic acid groups is disordered over two conformations with a site-occupancy ratio 0.719?(6):0.281?(6). In the crystal, pairs of O-H?O hydrogen bonds link the mol-ecules into infinite zigzag chains along [130].

The crystal structure shows ?-? stacking inter-actions [centroid-centroid distance = 3.70?(1)?Å] between the pyridinium rings and the phenyl-ene rings, generating a linear chain structure. The cation also forms two N-H?O hydrogen bonds to two nitrate groups.
