Project description:The complete molecule of the title Schiff base, C(26)H(18)Br(2)N(2), is generated by crystallographic twofold symmetry. The aromatic rings of the biphenyl-ene portion of the mol-ecule are twisted, as shown by the dihedral of 61.8?(1)° formed between them.

{N,N'-Bis[(E)-3-phenyl-allyl-idene]ethane-1,2-diamine}dichloridozinc(II).

Project description:In the title compound, [ZnCl(2)(C(20)H(20)N(2))], the Zn(II) atom is four coordinated in a distorted tetra-hedral geometry by two N atoms of the Schiff base ligand and by two Cl atoms.

(E)-2,2-Dimethyl-5-(3-phenyl-allyl-idene)-1,3-dioxane-4,6-dione.

Project description:The title compound, C(15)H(14)O(4), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and (Z)-3-phenyl-acryl-aldehyde in ethanol. The dioxane ring is in a sofa conformation with the C atom bonded to the two methyl groups forming the flap. With the exception of the flap atom and the methyl group C atoms, all other non-H atoms are essentially planar, with an r.m.s. deviation of 0.067?(1)?Å. The crystal structure is stabilized by weak inter-molecular C-H?O hydrogen bonds.

N,N'-Bis(4-chloro-benzyl-idene)-3,3'-dimeth-oxy-biphenyl-4,4'-diamine.

Project description:The title compound, C(28)H(22)Cl(2)N(2)O(2), crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules differ essentially in the orientation of the outer aromatic rings. These dihedral angles are 56.07?(13) and 27.62?(15)?Å for mol-ecules A and B, respectively. In the crystal, A mol-ecules are related as centrosymmetric pairs through a weak ?-? inter-action [centroid-centroid distance = 3.6959?(15)?Å]. There are also a number of inter-molecular C-H?O, C-H?N and C-H?? inter-actions present.

N,N'-Bis(4-bromo-benzyl-idene)-2,2-dimethyl-propane-1,3-diamine.

Project description:The mol-ecule of the title compound, C(19)H(20)Br(2)N(2), is a potential bidentate Schiff base ligand. The two benzene rings are inclined at a dihedral angle of 30.85 (8)°. An inter-esting feature of the crystal structure is a weak inter-molecular Br⋯Br [3.4752 (4) Å] inter-action which is shorter than the sum of the van der Waals radii of the Br atoms and links neighbouring mol-ecules into chains along the c axis. The crystal structure is further stabilized by inter-molecular C-H⋯π inter-actions.

N,N'-Bis(4-chloro-benzyl-idene)-2,2-dimethyl-propane-1,3-diamine.

Project description:The title compound, C(19)H(20)Cl(2)N(2), is a potential bidentate Schiff base ligand. Intra-molecular C-H⋯N hydrogen bonds form five-membered rings, generating S(5) ring motifs. Each imino functional group is coplanar with its adjacent benzene ring; the two benzene rings form a dihedral angle of 51.30 (4)°. An inter-esting feature of the crystal structure is weak inter-molecular Cl⋯Cl [3.4752 (4) Å] and Cl⋯N [3.2927 (9) Å] inter-actions. Inter-molecular Cl⋯N inter-actions link mol-ecules into dimers with R(2) (2)(22) ring motifs. The crystal structure is further stabilized by weak π-π [centroid-centroid distances = 3.6970 (6)-3.8560 (6) Å] inter-actions.

Project description:In the title compound, C(19)H(20)N(4)O(4), a potential bidentate Schiff base ligand, each imino (C=N) functional group is coplanar with the adjacent benzene ring.

Project description:The mol-ecule of the title Schiff base compound, C(19)H(18)Cl(4)N(2), has crystallographic twofold rotation symmetry, with one C atom lying on the rotation axis. The dihedral angle between the two symmetry-related benzene rings is 84.70 (2)°. The plane of the -C=N-C- group is twisted away from the benzene ring by 7.5 (1)°. In the crystal structure, weak inter-molecular Cl⋯Cl [3.4851 (3) Å] contacts link neighbouring mol-ecules into a two-dimensional network parallel to the bc plane.

N,N'-Bis(5-bromo-2-hydroxy-benzyl-idene)-2,2-dimethylpropane-1,3-diamine.

Project description:The crystal structure of the title Schiff base compound, C(19)H(20)Br(2)N(2)O(2), contains two crystallographically independent mol-ecules (A and B) in the asymmetric unit, with similar conformations. Intra-molecular O-H?N (× 4) and C-H?N (× 5) hydrogen bonds form six- and five-membered rings, producing S(6) and S(5) ring motifs, respectively. One of the N atoms in mol-ecule A acts as a trifurcated acceptor, the rest of the N atoms being bifurcated acceptors. The dihedral angles between the benzene rings in mol-ecules A and B are 47.83?(17) and 61.11?(17)°, respectively. The mol-ecular conformation is stabilized by intra-molecular O-H?N and C-H?N hydrogen bonds. The short distances between the centroids of the benzene rings [3.7799?(19)-3.890?(2)?Å] indicate the existence of ?-? inter-actions. In addition, the crystal structure is further stabilized by an inter-molecular C-H?O hydrogen bond, C-H?? inter-actions, and short inter-molecular Br?Br and Br?O contacts [3.4786?(5) and 3.149?(3)?Å, respectively].

Bis(?-biphenyl-2,2'-dicarboxyl-ato)bis-[(2,2'-bipyridine)copper(II)].

Project description:The title compound, [Cu(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)], is a centrosymmetric binuclear copper(II) complex, with a Cu?Cu separation of 6.136?(16)?Å. The Cu atom displays a cis-CuN(2)O(2) square-planar geometry, although two long (> 2.43?Å) Cu?O contacts complete a distorted cis-CuN(2)O(4) octa-hedron. Extensive C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.
