2,5-Bis(pyridinium-2-yl)-3,6-bis-(2-pyrid-yl)pyrazine bis-[tetra-chlorido-aurate(III)].

ABSTRACT: In the title compound, (C(24)H(18)N(6))[AuCl(4)](2), the cation is located on an inversion center. Each of the two independent Au(III) ions lies on an inversion center and has a distorted square-planar geometry. In the crystal, inter-molecular C-H?Cl hydrogen bonds, ?-? inter-actions [centroid-centroid distances = 3.5548?(16) and 3.7507?(16)?Å] and Au?? inter-actions [Au?centroid distance = 3.6424?(10)?Å] are effective in the stabilization of the structure, resulting in the formation of a supra-molecular structure. Intra-molecular N-H?N hydrogen bonds are present in the cation.

Bis{2-[2,5-bis-(pyridin-2-yl)-1H-imidazol-4-yl]pyridinium} tetra-cyanidoplatinate(II) tetra-hydrate.

Project description:The asymmetric unit of the title hydrated complex salt, (C18H14N5)2[Pt(CN)4]·4H2O, consists of one 2-[2,5-bis-(pyridin-2-yl)-1H-imidazol-4-yl]pyridinium cation, half a tetra-cyanidoplatinate(II) dianion, which is located about a crystallographic inversion center, and two water mol-ecules of crystallization. The Pt(II) atom has a square-planar coordination environment, with Pt-CCN distances of 1.992 (4) and 2.000 (4) Å. In the cation, there is an N-H⋯N hydrogen bond linking adjacent pyridinium and pyridine rings in positions 4 and 5. Despite this, the organic component is non-planar, as shown by the dihedral angles of 10.3 (2), 6.60 (19) and 15.66 (18)° between the planes of the central imidazole ring and the pyridine/pyridinium substituents in the 2-, 4- and 5-positions. In the crystal, cations and anions are linked via O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds, forming a three-dimensional network. Additional π-π, C-H⋯O and C-H⋯N contacts provide stabilization to the crystal lattice.

2,5-Bis[4-(dimethyl-amino)-phen-yl]-3,6-dimethyl-pyrazine.

Project description:The title compound, C(22)H(26)N(4), was prepared from p-dimethyl-amino-propiophenone in six steps. The mol-ecule has no crystallographic symmetry. The dihedral angles between the pyrazine ring and the phenyl rings are 35.81?(6) and 37.11?(8)°. The dimethyl-amino groups are essentially planar (sum of the bond angles at N = 359.3 and 359.9°) and nearly coplanar with the adjacent aromatic ring [dihedral angles = 5.54?(11) and 7.40?(3)°]. This effect and the short aniline C-N bonds can be rationalised in terms of charge transfer from the amino groups to the central pyrazine ring.

Bis[5-(2-pyrid-yl)pyrazine-2-carbonitrile]-silver(I) tetra-fluorido-borate.

Project description:In the title mononuclear complex, [Ag(C(10)H(6)N(4))(2)]BF(4), the Ag(I) atom adopts a square-planar N(4 )coordination geometry and is surrounded by two 5-(2-pyrid-yl)pyrazine-2-carbonitrile ligands. The tetra-fluorido-borate anions link the mononuclear cations through inter-molecular C-H⋯F hydrogen-bonding inter-actions, forming an infinite tape structure along [110]. Other weak inter-actions occur: π-π stacking with centroid-centroid distances of 3.820 (2) and 3.898 (1) Å between pyridyl rings and 3.610 (2) and 3.926 (2) Å between pyrazinyl rings as well as F⋯π contacts involving the tetra-fluorido-borate anions and pyrazine rings [F⋯centroid = 2.999 (3) Å]; these combine with the hydrogen-bonding inter-actions to link the mononuclear cations into a three-dimensional supra-molecular architecture.

1,2,4,5-Tetra-fluoro-3,6-diiodo-benzene-2,3-bis-(pyridin-2-yl)pyrazine (1/1).

Project description:The components of the title 1:1 co-crystal, C(14)H(10)N(4)·C(6)F(4)I(2), are connected via an N?I [2.959?(4)?Å] halogen bond, in which the N atom is part of the relatively electron-rich pyrazine ring. The C(6)F(4)I(2) mol-ecule is almost planar [r.m.s. deviation = 0.038?Å] but there are significant twists in the pyrazine derivative, as seen in the dihedral angles [31.3?(2) and 54.6?(2)°] formed between the pendant pyridyl rings and the central pyrazine ring. The bimolecular aggregates are sustained in the crystal by C-H?F and ?-? inter-actions [ring centroid(pyrid-yl)-ring centroid(benzene) = 3.678?(3)?Å].

4-(4-Pyrid-yl)pyridinium bis-(pyridine-2,6-dicarboxyl-ato)ferrate(III) tetra-hydrate.

Project description:In the title compound, (C(10)H(9)N(2))[Fe(C(7)H(3)NO(4))(2)]·4H(2)O or (bpyH)[Fe(pydc)(2)]·4H(2)O, the asymmetric unit contains an [Fe(pydc)(2)](-) (pydcH(2)= pyridine-2,6-dicarboxylic acid) anion, a protonated 4,4'-bipyridine as a counter-ion, (bpyH)(+), and four uncoordinated water mol-ecules. The anion is a six-coordinate complex with a distorted octa-hedral geometry around the Fe(III )atom. A wide range of non-covalent inter-actions, i.e. O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds, ion pairing, C-O⋯π [3.431 (2) Å] and C-H⋯π stacking inter-actions result in the formation of a three-dimensional network structure.

4-(4-Pyrid-yl)pyridinium bis-(pyridine-2,6-dicarboxyl-ato)chromium(III) tetra-hydrate.

Project description:The title compound, (C(10)H(9)N(2))[Cr(C(7)H(3)NO(4))(2)]·4H(2)O or (4,4'-bipyH)[Cr(pydc)(2)]·4H(2)O (where 4,4'-bipy is 4,4'-bipyridine and pydcH(2) is pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of chromium(III) chloride hexa-hydrate with pyridine-2,6-dicarboxylic acid and 4,4'-bipyridine in a 1:2:4 molar ratio in aqueous solution. This compound is composed of an anionic complex, [Cr(pydc)(2)](-), protonated 4,4'-bipyridine as a counter-ion, (4,4'-bipyH)(+), and four uncoordinated water mol-ecules. The anion is a six-coordinate complex with a distorted octa-hedral geometry around the Cr(III) atom, formed by two tridentate pyridine-2,6-dicarboxyl-ate, pydc(2-), groups. Inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, and C-O⋯π stacking inter-actions (with distances of 3.3390 (13) and 3.4575 (13) Å) connect the various components into a supra-molecular structure.

Bis(4-chloro-pyridinium) tetra-chlorido-nickelate(II).

Project description:In the title compound, (C(5)H(5)ClN)(2)[NiCl(4)], the dianion lies on a twofold rotation axis. Two cations are linked to each anion by classical N-H⋯Cl hydrogen bonds, and short Cl⋯Cl contacts and Cl⋯π stacking inter-actions [with distances of 3.376 (2) and 3.684 (2) Å, respectively] extend this pattern into a chain. The [NiCl(4)](2-) anion shows significant deviation from ideal tetra-hedral geometry.
