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

ABSTRACT: 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: ?-? 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?? 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.

Hexaaqua-copper(II) bis-(tetra-fluorido-borate)-pyrazine 1,4-dioxide (1/3).

Project description:The crystal structure of the title compound, [Cu(H2O)6](BF4)2·3C4H4N2O2, comprises discrete [Cu(H2O)6](2+) cations and BF4 (-) anions along with three equivalents of pyrazine 1,4-dioxide (pzdo). The hexa-aqua-copper(II) ion and all three pzdo mol-ecules lie about crystallographic inversion centers. The lattice is supported by an extensive hydrogen-bonding network. O-H?O hydrogen bonding between the [Cu(H2O)6](2+) and pzdo units creates a pseudo-hexa-gonal lattice parallel to the bc plane. The BF4 (-) anions lie in the voids of that lattice, held in place by O-H?F hydrogen bonds, and also generate BF4 (-)-pzdo-BF4 (-)-pzdo stacks via short F?N contacts [2.866?(3)-3.283?(4)?Å].

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

Project description: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.

Tetra-kis(triphenyl-phosphane-?P)silver(I) tetra-fluorido-borate.

Project description:The title complex, [Ag(C(18)H(15)P)(4)]BF(4), was prepared by the reaction of silver(I) tetra-fluorido-borate and triphenyl-phosphane in the presence of 1,2-bis-(pyridin-2-yl)ethyl-ene. The Ag(I) atom is tetra-hedrally coordinated by four P atoms from triphenyl-phosphane (PPh(3)) ligands. Due to symmetry, the tetra-fluorido-borate anion is disordered over three positions (each with one third occupancy). The tetra-fluorido-borate anion does not coordinate to the Ag(I) atom.

Project description:In the title complex, {[Cu(C(11)H(8)N(2)O)(2)](BF(4))(2)}(n), the Cu(II) ion is situated on an inversion centre and adopts an N(4)F(2) octa-hedral coordination geometry with four N atoms from four different bis-(pyridin-3-yl)methanone ligands at the equatorial sites and two independent tetra-fluoridoborate anions weakly bonded at the axial sites via two F atoms [Cu?F = 2.613?(3)?Å]. Chains with the bridging ligands are formed along the a axis. C-H?F inter-actions stabilize the structure. C-O?? inter-actions also occur.

The unit cell contains a half equivalent of an acetonitrile solvent mol-ecule per tetra-pyrazine-platinum(II) ion. The coordination geometry of the Pt(II) ion is almost square-planar, with the Pt atom residing on an inversion center. The BF(4) (-) counter-anion, located at a general position, has an idealized tetra-hedral geometry and an acetonitrile solvent mol-ecule, the methyl group of which is disordered over two equal positions, sits on a twofold rotation axis.

(Nitrato-?O)bis-[5-(pyridin-2-yl)pyrazine-2-carbonitrile-?N,N]silver(I).

Project description:In the mononuclear title complex, [Ag(NO(3))(C(10)H(6)N(4))(2)], two ?(2)N:N'-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the Ag(I) atom, forming an N(4)O square-pyramidal coordination geometry with one nitrate anion bonding at the apical site. The two heterocyclic rings of the 5-(2-pyridin-2--yl)pyrazine-2-carbonitrile ligand are almost coplanar [dihedral angle = 5.63?(8)°], and the two chelating ligands are in an anti relationship. The mononuclear units are inter-connected along [010] through C-H?O(nitrate) and C-H?N(cyano) inter-actions, forming an infinite chain. The mononuclear units are stacked along the a axis and inter-connected via inter-molecular ?-? stacking inter-actions between adjacent pyridine and pyrazine rings [centroid-centroid distances = 3.984?(2) and 3.595?(3)?Å], thus forming a three-dimensional supra-molecular structure.

Bis{2-[(pyridin-4-yl-?N)sulfan-yl]pyrazine}-silver(I) tetra-fluoridoborate.

Project description:In the title mononuclear complex, [Ag(C(9)H(7)N(3)S)(2)]BF(4), the Ag(I) ion adopts a virtually linear coordination geometry [N-Ag-N = 178.06?(11)°] with the two ligands bound to the metal atom via the pyridine N atoms. The metal-coordinated pyridine rings are almost coplanar, making a dihedral angle of 1.5?(2)°, while the two pendent pyrazine rings are arranged on the same side of the N-Ag-N line. Along the a axis, the mononuclear coordination units are stacked with ?-? inter-actions between the pyridine rings [centroid-centroid distance = 3.569?(4)?Å], leading to infinite chains. The chains are inter-connected through inter-molecular N(pyrazine)??(pyrazine) inter-actions forming layers parallel to the ab plane [N?centroid = 3.268?(5)?Å]. These layers are further stacked along the c-axis direction, furnishing a three-dimensional supra-molecular framework with the tetra-fluoridoborate anions embedded within the inter-stices.
