1,2-Bis(di-2-pyridylphosphino-yl)ethane.

ABSTRACT: The crystal structure of the title compound, C(22)H(20)N(4)O(2)P(2), consists of two independent half-mol-ecules, both of which lie on crystallographic inversion centres. There are no significant differences between the two mol-ecules.

1,1'-(Ethane-1,2-di-yl)bis-(1,4,7-triazonane).

Project description:In the centrosymmetric title compound (dtne), C(14)H(32)N(6), two 1,4,7-triaza-cyclo-nonane (tacn, or 1,4,7-triazonane) moieties are linked together each at an amino position by a single ethyl-ene spacer. The mol-ecular packing is supported by pairs of inter-molecular N-H?N hydrogen bonds, which form R(2) (2)(22) ring motifs and link the mol-ecules into infinite chains running parallel to the a axis.

1,1'-(Ethane-1,2-di-yl)dipyridinium bis-(iodate).

Project description:The title salt, C(12)H(14)N(2) (2+)·2IO(3) (-), exhibits two crystallographically independent iodate anions, the I atoms of which are each in a trigonal-pyramidal environment. In the dication, the two pyridine rings adopt an anti conformation with respect to each other; the angle between these two rings is 3.84 (19)°. In the crystal structure, C-H⋯O hydrogen bonds between the cations and anions lead to the formation of layers arranged parallel to the ab plane. I⋯O halogen bonds [R(2) (2)(4) graph-set motif] range between 2.873 (2) and 3.036 (3) Å and connect neighbouring IO(3) (-) anions with each other along [100], so as to create a three-dimensional network.

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.

Project description:The complete molecule of the title compound, C(16)H(18)N(4)S(2), is generated by crystallographic inversion symmetry. The dihedral angle between the phenyl ring and the thio-urea group is 52.9?(4)°. The crystal structure displays inter-molecular N-H?S hydrogen bonding, which generates sheets in the ab plane.

N,N'-(Ethane-1,2-di-yl)bis-(methane-sulfon-amide).

Project description:The mol-ecular structure of the title compound, C4H12N2O4S2, has crystallographic inversion symmetry. The central N-C-C-N moiety was refined as disordered over two sets of sites with an approximate occupancy ratio of 3:1 [0.742 (15):0.258 (15). In the crystal, N-H⋯O hydrogen bonds link adjacent mol-ecules into a thick sheet structure parallel to the b-axis direction.

N,N'-{[Ethane-1,2-diylbis(-oxy)]bis-(ethane-2,1-di-yl)}bis-(4-methyl-benzene-sulfonamide).

Project description:The asymmetric unit of the title compound, C(20)H(28)N(2)O(6)S(2), contains one half-mol-ecule, related to the other half by a twofold rotation axis. The two aromatic rings of the mol-ecule make a dihedral angle of 50.91?(7)°. The O-CH(2)-CH(2)-O and N-CH(2)-CH(2)-O fragments both adopt gauche conformations, with torsion angles of 76.0?(4) and 70.4?(3)°, respectively. In the crystal, adjacent mol-ecules are linked through N-H?O hydrogen bonds into chains along the a-axis direction. The chains are further connected via C-H?O inter-actions into a two-dimensional supra-molecular network in the ac plane.

Crystal structure of 4,4'-(ethane-1,2-di-yl)bis-(2,6-di-bromo-aniline).

Project description:In the title compound, C14H12Br4N2, the mol-ecule lies across an inversion center and hence the benzene rings are strictly coplanar. In the crystal, mol-ecules are linked by N-H⋯N and weak N-H⋯Br hydrogen bonds, forming a two-dimensional network parallel to (101). In addition, type II Br⋯Br inter-actions [3.625 (4) Å] complete a three-dimensional supra-molecular network.

Project description:The title compound, C(18)H(20)N(2)O(2), was prepared by Mannich-type reaction of phenol, ethane-1,2-diamine and formaldehyde.

In the crystal, weak C-H?O hydrogen bonds link the mol-ecules into dimers. These dimers are further connected via C-H?? contacts.
