ABSTRACT: The title azo mol-ecule, C16H9Br3N2O, adopts a trans conformation with respect to the azo N=N double bond. An intra-molecular O-H?N hydrogen bond forms an S(6) ring motif. The dihedral angle between the naphthalene ring system and the benzene ring is 33.80?(16)°. In the crystal, mol-ecules are stacked in columns along the a axis by ?-? inter-actions [centroid-centroid distances = 3.815?(3) and 3.990?(3)?Å].

The title azo mol-ecule, C16H9Br3N2O, adopts a trans conformation with respect to the azo N=N double bond. An intra-molecular O-H⋯N hydrogen bond forms an S(6) ring motif. The dihedral angle between the naphthalene ring system and the benzene ring is 33.80 (16)°. In the crystal, mol-ecules are stacked in columns along the a axis by π-π inter-actions [centroid-centroid distances = 3.815 (3) and 3.990 (3) Å]. ...[more]

Project description:In the title compound, [Cu(C16H8Br3N2O)2]·C2H6OS, the CuII atom is tetra-coordinated in a square-planar coordination, being surrounded by two N atoms and two O atoms from two N,O-bidentate (E)-1-[(2,4,6-tri-bromo-phen-yl)diazen-yl]naphthalen-2-olate ligands. The two N atoms and two O atoms around the metal center are trans to each other, with an O-Cu-O bond angle of 177.90?(16)° and a N-Cu-N bond angle of 177.8?(2)°. The average distances between the CuII atom and the coordinated O and N atoms are 1.892?(4) and 1.976?(4)?Å, respectively. In the crystal, complexes are linked by C-H?O hydrogen bonds and by ?-? inter-actions involving adjacent naphthalene ring systems [centroid-centroid distance = 3.679?(4)?Å]. The disordered DMSO mol-ecules inter-act weakly with the complex mol-ecules, being positioned in the voids left by the packing arrangement of the square-planar complexes. The DMSO solvent mol-ecule is disordered over two positions with occupancies of 0.70 and 0.30.

1-[(4-Bromo-phen-yl)(morpholin-4-yl)meth-yl]naphthalen-2-ol.

Project description:The title compound, C(21)H(20)BrNO(2), was obtained from a condensation reaction of 4-bromo-benzaldehyde, 2-naphthol and morpholine. The mol-ecular conformation is stabilized by an intra-molecular O-H?N hydrogen bond, closing a six-membered ring. The dihedral angle between the naphthalene ring system and the benzene ring is 76.72?(8)°. In addition to the intra-molecular hydrogen bond, the O-H groups of centrosymmetrically related mol-ecules form short inter-molecular H?O contacts of 2.59?Å. These mol-ecules are also linked by pairs of C-H?O inter-actions, generating an R(2) (2)(14) motif.

1-[Amino-(4-chloro-phen-yl)meth-yl]-6-bromo-naphthalen-2-ol.

Project description:In the title compound, C(17)H(13)BrClNO, the dihedral angle between the naphthol ring system and the chloro-benzene ring is 76.59?(11)°. This twisted conformation is supported by an intra-molecular O-H?N hydrogen bond. In the crystal, [100] chains arise, with adjacent mol-ecules linked by an N-H?O hydrogen bond, a C-H?? inter-action and an aromatic ?-? stacking contact [centroid-to-centroid separation = 3.783?(2)?Å]. Weak C-H?O inter-actions also occur.

Crystal structures of a copper(II) and the isotypic nickel(II) and palladium(II) complexes of the ligand (E)-1-[(2,4,6-tri-bromo-phen-yl)diazen-yl]naphthalen-2-ol.

Project description:In the copper(II) complex, bis-{(E)-1-[(2,4,6-tri-bromo-phen-yl)diazen-yl]naph-thalen-2-olato}copper(II), [Cu(C16H8Br3N2O)2], (I), the metal cation is coord-inated by two N atoms and two O atoms from two bidentate (E)-1-[(2,4,6-tri-bromo-phen-yl)diazen-yl]naphthalen-2-olate ligands, forming a slightly distorted square-planar environment. In one of the ligands, the tri-bromo-benzene ring is inclined to the naphthalene ring system by 37.4?(5)°, creating a weak intra-molecular Cu?Br inter-action [3.134?(2)?Å], while in the other ligand, the tri-bromo-benzene ring is inclined to the naphthalene ring system by 72.1?(6)°. In the isotypic nickel(II) and palladium(II) complexes, namely bis-{(E)-1-[(2,4,6-tri-bromo-phen-yl)diazen-yl]naphthalen-2-olato}nickel(II), [Ni(C16H8Br3N2O)2], (II), and bis-{(E)-1-[(2,4,6-tri-bromo-phen-yl)diazen-yl]naphthalen-2-olato}palladium(II), [Pd(C16H8Br3N2O)2], (III), respectively, the metal atoms are located on centres of inversion, hence the metal coordination spheres have perfect square-planar geometries. The tri-bromo-benzene rings are inclined to the naphthalene ring systems by 80.79?(18)° in (II) and by 80.8?(3)° in (III). In the crystal of (I), mol-ecules are linked by C-H?Br hydrogen bonds, forming chains along [010]. The chains are linked by C-H?? inter-actions, forming sheets parallel to (011). In the crystals of (II) and (III), mol-ecules are linked by C-H?? inter-actions, forming slabs parallel to (10-1). For the copper(II) complex (I), a region of disordered electron density was corrected for using the SQUEEZE routine in PLATON [Spek (2015 ?). Acta Cryst. C71, 9-18]. The formula mass and unit-cell characteristics of the disordered solvent mol-ecules were not taken into account during refinement.
