(E)-1,2-Bis(4-methyl-phen-yl)ethane-1,2-dione.

ABSTRACT: In the mol-ecule of the title compound, C(16)H(14)O(2), a substituted benzil, the dicarbonyl unit has an s-trans conformation. This conformation is substanti-ated by the O-C-C-O torsion angle of 108.16?(15)°. The dihedral angle between the two aromatic rings is 72.00?(6)°. In the crystal structure, neighbouring mol-ecules are linked together by weak inter-molecular C-H?O hydrogen bonds and weak inter-molecular C-H?? inter-actions. In addition, the crystal structure is further stabilized by inter-molecular ?-? inter-actions with centroid-centroid distances in the range 3.6000?(8)-3.8341?(8)?Å.

(E)-1,2-Bis(4-fluoro-phen-yl)ethane-1,2-dione.

Project description:The title compound, C(14)H(8)F(2)O(2), is a substituted benzil with an s-trans conformation of the dicarbonyl unit. This conformation is also shown by the O-C-C-O torsion angle of -110.65 (12)°. An unusual feature of the structure is the length, 1.536 (2) Å, of the central C-C bond connecting the carbonyl units, which is significantly longer than a normal Csp(2)-Csp(2) single bond. This is probably the result of decreasing the unfavourable vicinal dipole-dipole inter-actions by increasing the distance between the two electronegative O atoms [O⋯O = 3.1867 (12) Å] and allowing orbital overlap of the dione with the π system of the benzene rings. The dihedral angle between the aromatic rings is 64.74 (5)°. In the crystal structure, neighbouring mol-ecules are linked together by weak inter-molecular C-H⋯O (× 2) hydrogen bonds. In addition, the crystal structure is further stabilized by inter-molecular π-π inter-actions with centroid-centroid distances in the range 3.6416 (6)-3.7150 (7) Å.

1,2-Bis(2,4,6-trinitro-phen-yl)ethane.

Project description:The title compound, C(14)H(8)N(6)O(12), is centrosymmetric, the mid-point of the central C-C bond being located on an inversion centre. Two of the three independent nitro groups are disordered over two sites, with a site-occupancy ratio of 0.513?(3):0.487?(3). Weak inter-molecular C-H?O hydrogen bonding is present in the crystal structure.

1,1'-(Ethane-1,2-di-yl)bis-(indoline-2,3-dione).

Project description:The mol-ecule of the title compound, C(18)H(12)N(2)O(4), is situated on a crystallographic centre of symmetry. The mol-ecule has a zigzag structure, with two parallel symmetry-related indoline-2,3-dione fragments linked by an ethyl-ene group at each N atom. In the crystal, the mol-ecules stack in columns along the b axis. There are two such columns in the structure. The mol-ecules within each column are parallel; however, the mol-ecules in the two columns differ in the respective orientation of the indoline-2,3-dione fragments. In one column, they are approximately parallel to (112), while in the other they are approximately parallel to (12). The inter-planar angle between the indoline-2,3-dione fragments in the two columns is 80.83?(3)°. The mol-ecules within each column are related by mutual displacement of their centres of symmetry, that is (0, ±1/2, ±1/2). The packing between the mol-ecules is provided by weak inter-actions only, viz. C-H?O hydrogen bonds and ?-? [centroid-centroid distance = 3.8745?(8)?Å] and C=O?? inter-actions.

1,2-Bis{bis-[4-(trifluoro-meth-yl)phen-yl]phosphino}ethane.

Project description:Crystals of the title compound, C(30)H(20)F(12)P(2) or R(2)PCH(2)CH(2)PR(2) (R = 4-C(6)H(4)CF(3)), were inadvertently prepared while attempting to recrystallize a crude sample of trans-Re(Cl)(N(2))(R(2)PCH(2)CH(2)PR(2))(2) from diethyl ether. The molecule lies on a center of inversion. One of the rings lies approximately in the P-C-C-P plane; the dihedral angle is 174.53°.The other ring is not quite perpendicular; the dihedral angle is 71.1°. The compound is isostructural with the R = Ph, 4-C(6)H(4)CH(3) and 4-C(6)H(4)CH(2)CH(3) analogues. It is well known that the basicity of phosphines and diphosphines can be altered by changing the electron-donating ability of R; however, the structural parameters for the title compound do not significantly differ from those of the aforementioned substituted-phenyl compounds.

Project description:The crystal structure of the title compound, C(20)H(15)FN(2)O(2), contains two crystallographically independent mol-ecules, which are related by a pseudo-inversion center and linked into dimers via inter-molecular N-H?N hydrogen bonds.

The 4-fluoro-phenyl ring of mol-ecule B makes dihedral angles of 8.50?(16) and 64.59?(15)°, respectively, with the phenyl and pyridine rings.

The dihedral angle between the two pyridine rings is 1.37?(14)° and between the two phenyl rings is 3.64?(16)°.
