1,5-Diamino-2,6-dibromo-9,10-anthraquinone.

ABSTRACT: In the title compound, C(14)H(8)Br(2)N(2)O(2), the mol-ecular structure features intra-molecular N-H?O [2.639?(2)?Å and 130°] and N-H?Br [3.053?(2)?Å and 114°] hydrogen bonding. Due to inversion symmetry, the asymmetric part of the unit cell consits of one half-mol-ecule. In the crystal, inversion dimers linked by pairs of N-H?O [2.955?(2)?Å and 135°] hydrogen bonds occur. The structure also features C=O?? [3.228?(2)?Å] and Br?Br [3.569?(1)?Å] contacts.

In the title compound, C(14)H(8)Br(2)N(2)O(2), the mol-ecular structure features intra-molecular N-H⋯O [2.639 (2) Å and 130°] and N-H⋯Br [3.053 (2) Å and 114°] hydrogen bonding. Due to inversion symmetry, the asymmetric part of the unit cell consits of one half-mol-ecule. In the crystal, inversion dimers linked by pairs of N-H⋯O [2.955 (2) Å and 135°] hydrogen bonds occur. The structure also features C=O⋯π [3.228 (2) Å] and Br⋯Br [3.569 (1) Å] contacts. ...[more]

2,6-Dimeth-oxy-9,10-anthraquinone.

Project description:The title compound, C(16)H(12)O(4), crystallizes with two half-mol-ecules in the asymmetric unit, each of which is completed by a crystallographic inversion center. The two crystallographically independent mol-ecules have almost the same geometry and are almost planar [maximum deviations = 0.018?(3) and 0.049?(3)?Å]. They adopt a conformation in which the C(meth-yl)-O bonds are directed along the mol-ecular short axis [C-C-O-C torsion angles of 179.6?(2) and 178.0?(2)°]. In the crystal, the mol-ecular packing is characterized by a combination of a columnar stacking and a herringbone-like arrangement. The mol-ecules form slipped ?-stacks along the b axis, in which there are two kinds of columns differing from each other in their slippage. The inter-planar distances between neighboring mol-ecules are 3.493?(3) for one column and 3.451?(2)?Å for the other.

Bis(2,6-diamino-3,5-dibromo-pyridinium) hexa-bromidostannate(IV).

Project description:The asymmetric unit of the title compound, (C(5)H(6)Br(2)N(3))(2)[SnBr(6)], contains one cation and one half-anion in which the Sn atom is located on a crystallographic centre of inversion and is in a quasi-octa-hedral geometry. The crystal structure is assembled via hydrogen-bonding inter-actions of two kinds, N(pyridine/amine)-H⋯Br-Sn, along with C-Br⋯Br-Sn interactions [3.4925 (19) Å]. The cations are involved in π-π stacking, which adds an extra supra-molecularity as it presents a strong case of offset-face-to-face motifs [centroid-centroid distance = 3.577 (3) Å]. The inter-molecular hydrogen bonds, short Br⋯Br inter-actions and π-π stacking result in the formation of a three-dimensional supra-molecular architecture.

Tetra-kis(2,6-diamino-pyridinium) diphthalate 2,6-diamino-pyridine.

Project description:In the title compound, 4C(5)H(8)N(3) (+)·2C(8)H(4)O(4) (2-)·C(5)H(7)N(3), the asymmetric unit consists of two protonated diamino-pyridine cations, one phthalate anion and one half of a diamino-pyridine mol-ecule, which has twofold rotation symmetry and is disordered over two positions with a site-occupancy ratio of 0.534?(3):0.466?(3). In the disordered structure, both pyridine rings are essentially planar, with maximum deviations of 0.011?(2) and 0.006?(2)?Å, and these two rings are inclined to one another at a dihedral angle of 79.86?(10)°. In the crystal structure, inter-molecular N-H?O and C-H?O hydrogen bonds link the ions and mol-ecules into a three-dimensional network. The structure is further stabilized by C-H?? inter-actions.
