Bis[1-(2-eth-oxy-phen-yl)-3-(4-nitro-phen-yl)triazenido]mercury(II).

ABSTRACT: In the title compound, [Hg(C(14)H(13)N(4)O(3))(2)], the central Hg atom (site symmetry 2) is six-coordinated by two tridentate 1-(2-eth-oxy-phen-yl)-3-(4-nitro-phen-yl)triazenide ligands through two N and one O atoms. The mononuclear complex mol-ecules are connected into two parallel chains by inter-molecular C-H⋯O hydrogen-bonding inter-actions. These chains are connected to each other by face-to-edge C-H⋯π inter-actions between the CH of the ethoxy groups and the aromatic rings, resulting in a two-dimensional architecture in the ac plane.

Project description:In the title compound, [Hg(C(14)H(13)N(4)O(3))Cl], the Hg(II) atom is four-coordinated by one O atom and two N atoms from a tridentate 1-(2-eth-oxy-phen-yl)-3-(4-nitro-phen-yl)triazenide ligand and one terminal chloride ion in a distorted square-planar geometry. In the crystal structure, the mononuclear complexes are linked into pairs through C-H⋯O and C-H⋯Cl hydrogen bonds as well as π-π and C-H⋯π stacking inter-actions. In addition, weak Hg-μ(6)-arene π-inter-actions [mean distance of 3.667 (2) Å] are present between these dimers. The π-π stacking inter-actions are between aromatic rings with a centroid-centroid distance of 3.884 (2) Å. Moreover, edge-to-face inter-actions are present between eth-oxy CH groups and aromatic rings with H⋯π distances of 2.81 Å.

Bis[1,3-bis-(2-cyano-phen-yl)triazenido]mercury(II).

Project description:In the title compound, [Hg(C(14)H(8)N(5))(2)], the central atom is four-coordinated by two bidentate 1,3-bis-(2-cyano-phen-yl)triazenide ligands in a distorted square-planar geometry. The asymmteric unit is composed of one ligand molecule and one Hg(II) ion, which is disordered over two sites, one lying on an inversion center and the other on a general position with site-occupancy factors of 0.2378?(7) and 0.3811?(7), respectively. The monomeric mol-ecules of the complex are linked into pairs through non-classical C-H?N hydrogen bonds. The resulting dimeric units are assembled by translation along the crystallographic c axis into chains linked through secondary ?-? inter-actions [centroid-centroid distances = 3.685?(2) and 3.574?(2)?Å], as well as C-H?? stacking inter-actions, resulting in a two-dimensional architecture.

Bis[?-O-isopropyl (4-eth-oxy-phen-yl)dithio-phospho-nato-?(2) S:S']bis-{[O-iso-propyl (4-eth-oxy-phen-yl)dithio-phos-phonato-?(2) S,S']mercury(II)}.

Project description:The title compound, [Hg2(C11H16O2PS2)4], is a dinuclear complex with a distorted tetra-hedral geometry around each Hg(II) atom. Although the two Hg(II) atoms are surrounded by the same ligand, two different coordination modes are observed: one is chelating and the other bridging. The Hg-S bonds form two distinct pairs of long and short bonds. One pair includes both chelating and bridging Hg-S bonds with approximately equal bond lengths of 2.4042?(8) and 2.3997?(7)?Å, respectively. The other pair is significantly longer at 2.9361?(9) and 2.8105?(8)?Å, respectively. This pattern forms a center of inversion through the mol-ecule with an equal and opposite effect occurring at the other Hg(II) atom. The S-Hg-S angles vary widely from 76.26?(2) to 154.65?(3)°, indicative of a distorted tetra-hedral arrangement of the S atoms around the Hg(II) atom. The P-S bond lengths are 1.9681?(10) and 2.0519?(11)°, clearly indicating partial double-bond character in the former. The mol-ecule contains an inversion center situated between the two Hg(II) atoms.

[1,3-Bis(2-ethoxy-phen-yl)triazenido]bromidomercury(II).

Project description:To the central atom of the title compound, [HgBr(C(16)H(18)N(3)O(2))], is attached one bromide ion and a 1,3-bis-(2-ethoxy-phen-yl)triazenide ligand through one O and two N atoms, forming a distorted square-planar geometry around the Hg(II) atom. The mononuclear complexes are linked into centrosymmetric dimers by non-classical inter-molecular C-H?N hydrogen bonds and by weak Hg-?(3)-arene ?-inter-actions [mean distance = 3.434?(3)?Å]. The resulting dimeric units are assembled into zigzag chains by translation along the crystallographic c axis through secondary C-H?? edge-to-face benzene ring inter-actions.

Project description:In the title compound, [Cd(C(14)H(14)N(3)O(2))(2)(CH(3)OH)(2)], each cadmium(II) center is six-coordinated by an N atom and an O atom of two 1,3-bis-(2-methoxy-phen-yl)triazene ligands and by the O atoms of two methanol mol-ecules. The distorted octa-hedral coordination geometry of the Cd atom has two N and two O atoms in the equatorial plane, and two O atoms in axial positions. The complex is stabilized by intra-molecular O-H?O and O-H?N hydrogen bonds. In the crystal structure the complexes are linked into chains via inter-molecular C-H?? stacking inter-actions. One of the methanol C atoms is disordered with ouccupancies of 0.7:0.3.

3-(2-Eth-oxy-phen-yl)-1-(3-nitro-phen-yl)triaz-1-ene.

Project description:The title compound, C(14)H(14)N(4)O(3), exhibits a trans geometry about the N=N double bond in the triazene unit. The mol-ecule is approximately planar (r.m.s. deviation = 0.044?Å for all non-H atoms). An intra-molecular N-H?O hydrogen bond occurs. In the crystal, C-H?N hydrogen bonds lead to the formation of dimers which are, in turn, connected to each other by C-H?O hydrogen bonds, forming infinite chains of R(2) (2)(8) graph-set motif.
