The average endocyclic angles (Se-Car-Car; ar = aromatic) facing the Se atom are 120.0?(3) and 119.4?(3)°. The Se atom is essentially coplanar with the benzene rings, with Se-Car-Car-Car torsion angles of -179.2?(3) and -179.7?(3)°. In the crystal, mol-ecules are linked via C-H?O hydrogen bonds forming chains propagating along the a-axis direction. The chains are linked via C-H?? inter-actions, forming a three-dimensional network.

Crystal structure and Hirshfeld surface analysis of (2E,2'E)-1,1'-[seleno-bis-(4,1-phenyl-ene)]bis-[3-(4-chloro-phen-yl)prop-2-en-1-one].

Project description:In the title com-pound, C30H20Cl2O2Se, the C-Se-C angle is 99.0 (2)°, with the dihedral angle between the planes of the attached benzene rings being 79.1 (3)°. The average endocyclic angles (Se-C-C) facing the Se atom are 122.1 (5) and 122.2 (5)°. The Se atom is essentially coplanar with the attached benzene rings, deviating by 0.075 (1) and 0.091 (1) Å. In the two phenyl-ene(4-chloro-phen-yl)prop-2-en-1-one units, the benzene rings are inclined to each other by 44.6 (3) and 7.8 (3)°. In the crystal, the mol-ecules stack up the a axis, forming layers parallel to the ac plane. There are no significant classical inter-molecular inter-actions present. Hirshfeld surface analysis, two-dimensional fingerprint plots and the mol-ecular electrostatic potential surface were used to analyse the crystal packing. The Hirshfeld surface analysis suggests that the most significant contributions to the crystal packing are by C⋯H/H⋯C contacts (17.7%).

Crystal structure of N,N'-(1,2-phenyl-ene)bis-(2-chloro-acetamide).

Project description:In the title compound, C10H10Cl2N2O2, the secondary amide groups are differently twisted relative to the benzene ring, with dihedral angles between the respective planes of 21.03?(2) and 81.22?(2)°. In the crystal, the mol-ecules are connected by N-H?O and C-H?O hydrogen bonds, forming a two-dimensional polymeric network parallel to (001). One of the amide carbonyl O atoms accepts two H atoms in N-H?O and C-H?O inter-actions, forming an R 2 (2)(6) ring motif.

Crystal structure and Hirshfeld surface analysis of 2,2'-(phenyl-aza-nedi-yl)bis-(1-phenyl-ethan-1-one).

Project description:The whole mol-ecule of the title compound, C22H19NO2, is generated by twofold rotational symmetry. The N atom exhibits a trigonal-planar geometry and is located on the twofold rotation axis. In the crystal, mol-ecules are linked by C-H⋯O contacts with R 2 2(12) ring motifs, and C-H⋯π inter-actions, resulting in ribbons along the c-axis direction. van der Waals inter-actions between these ribbons consolidate the mol-ecular packing. Hirshfeld surface analysis indicates that the greatest contributions to the crystal packing are from H⋯H (45.5%), C⋯H/H⋯C (38.2%) and O⋯H/H⋯O (16.0%) inter-actions.

Project description:The centroid of the central aromatic ring of the title mol-ecule, C(24)H(22)O(4), is located on an inversion center. The dihedral angle between the central and terminal benzene rings is 75.00 (7)°. In the crystal, mol-ecules are linked through C-H⋯O hydrogen bonds into chains along [121]. The chains are connected into layers via C-H⋯π inter-actions.

1,1'-{[1,4-Phenyl-enebis(methyl-ene)]bis-(-oxy)bis-(3,1-phenyl-ene)}diethanone.

Project description:In the title compound, C(24)H(22)O(4), the centroid of the central benzene ring lies on a special position of 2/m site symmetry, while the terminal aromatic rings are located on a mirror plane. The central and terminal benzene rings are perpendic-ular to each other. In the crystal, the mol-ecules are connected via C-H⋯O hydrogen bonds into a three-dimensional polymeric structure. The network is further consolidated by a C-H⋯π inter-action.

1,1'-{2,2'-[1,4-Phenyl-enebis(methyl-ene)]bis-(-oxy)bis-(2,1-phenyl-ene)}diethanone.

Project description:The asymmetric unit of the title compound, C(24)H(22)O(4), contains one half-mol-ecule, the other half being generated by a crystallographic center of inversion. The central benzene ring makes a dihedral angle of 72.49 (5)° with the terminal benzene ring. In the crystal, adjacent mol-ecules are linked through C-H⋯O inter-actions, forming a sheet structure parallel to the bc plane. The sheets are stacked along the a axis via π-π inter-actions formed between the terminal benzene rings [centroid-centroid separation = 3.7276 (6) Å].

1,1'-[(5-Hy-droxy-methyl-1,3-phenyl-ene)bis-(methyl-ene)]dipyridin-4(1H)-one monohydrate.

Project description:The asymmetric unit of the title compound, C(19)H(18)N(2)O(3), comprises a whole organic dipyridinone mol-ecule plus a water mol-ecule of crystallization. The planes of the pyridinone rings are approximately perpendicular with the plane of the central aromatic ring [dihedral angles = 80.68 (8) and 83.65 (8)°]. The C-O bond of the hy-droxy group subtends an angle of 31.71 (10)° with the plane through the central aromatic ring. The crystal packing is mediated by the presence of several O-H⋯O hydrogen-bonding inter-actions and while the water mol-ecules form a C(2) (1)(4) chain parallel to the c axis of the unit cell, the pendant hy-droxy groups are engaged in O-H⋯O=C hydrogen bonds described by a C(1) (1)(12) graph-set motif which runs parallel to the a axis.

Crystal structure of a di-aryl carbonate: 1,3-phenyl-ene bis-(phenyl carbonate).

Project description:The whole mol-ecule of the title compound, C20H14O6, is generated by mirror symmetry, the mirror bis-ecting the central benzene ring. The carbonate groups adopt an s-cis-s-cis conformation, with torsion angles of 58.7 (2) and 116.32 (15)°. The crystal structure of 1,3-phenyl-ene bis-(phenyl carbonate) contains no strong hydrogen bonds, though weak C-H⋯O and offset π-π inter-actions are observed, forming layers parallel to the ac plane.

2-[(4-Chloro-phen-yl)sulfan-yl]-2-meth-oxy-1-phenyl-ethan-1-one: crystal structure and Hirshfeld surface analysis.

Project description:The title compound, C15H13ClO2S, comprises (4-chloro-phen-yl)sulfanyl, benzaldehyde and meth-oxy residues linked at a chiral methine-C atom (the crystal is racemic). A twist in the methine-C-C(carbon-yl) bond [O-C-C-O torsion angle = 19.3 (7)°] leads to a dihedral angle of 22.2 (5)° between the benzaldehyde and methine+meth-oxy residues. The chloro-benzene ring is folded to lie over the O atoms, with the dihedral angle between the benzene rings being 42.9 (2)°. In the crystal, the carbonyl-O atom accepts two C-H⋯O inter-actions with methyl- and methine-C-H atoms being the donors. The result is an helical supra-molecular chain aligned along the c axis; chains pack with no directional inter-actions between them. An analysis of the Hirshfeld surface points to the important contributions of weak H⋯H and C⋯C contacts to the mol-ecular packing.
