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.

N,N'-Bis(3,4-dimethoxy-benzyl-idene)butane-1,4-diamine.

Project description:The title Schiff base compound, C(22)H(28)N(2)O(4), was synthesized by the reaction of 3,4-dimethoxy-benzaldehyde and 1,4-diamino-butane in methanol.

Project description:In the title Schiff base, C(17)H(14)Cl(4)N(2), the atoms of one of the 2,6-dichloro-benzyl-idene units and the central 1,2-diamino-propane grouping are disordered over two sets of sites in a 0.8838 (12):0.1162 (12) ratio.

Diazido-bis(propane-1,3-diamine)copper(II).

Project description:In the title complex, [Cu(N(3))(2)(C(3)H(10)N(2))(2)], the Cu(II) ion resides on a centre of symmetry and is in a Jahn-Teller distorted octa-hedral coordination environment comprising two N atoms from azide anions in axial positions and four N atoms from propane-1,3-diamine (tn) ligands in equatorial positions. Inter-molecular N-H?N hydrogen bonds produce R(2) (1)(6), R(2) (2)(8), R(2) (2)(12) and R(4) (2)(8) rings, generating a two-dimensional layer.

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].
