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

ABSTRACT: 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.

1,3-Bis(pyridin-2-yl)-1H-benzimidazol-3-ium tetra-fluoridoborate.

Project description:The asymmetric unit of the title compound, C(17)H(13)N(4) (+)·BF(4) (-), contains one half of the benzimidazolium cation and one half of the tetra-fluoridoborate anion, with crystallographic mirror planes bis-ecting the mol-ecules. One F atom of the tetra-fluoridoborate is equally disordered about a crystallographic mirror plane. In the crystal, C-H?F inter-actions link the cations and anions into layers parallel to (100). The crystal packing is further stabilized by F?? contacts involving the tetra-fluoridoborate anions and the five-membered rings [F?centroid = 2.811?(2)?Å].

trans-Diaqua-bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole]nickel(II) bis-(tetra-fluoridoborate).

Project description:The bidentate 1,3,4-thia-diazole ligand, namely, 2,5-bis-(2-pyrid-yl)-1,3,4-thia-diazole (denoted L), untested as a polydentate ligand, has been found to form the monomeric title complex, [Ni(C(12)H(8)N(4)S)(2)(H(2)O)(2)](BF(4))(2). The complex shows an octa-hedral environment of the nickel cation in which the Ni(2+) ion is located on a center of symmetry, linked to two ligands and two water molecules. In this 1:2 complex (one metal for two organic ligands) each thia-diazole ligand uses one pyridyl and one thia-diazole N atom for chelate binding. In the second pyridyl substituent, the N atom is oriented towards the same direction as the S atom of the 1,3,4-thiadiazole ring. The mean plane of the thia-diazole and pyridyl rings linked to the nickel cation forms a dihedral angle with the other pyridine ring of 18.63?(8)°. The tetra-fluorido-borate ions can be regarded as free anions in the crystal lattice. Nevertheless, they are involved in an infinite two-dimensional network parallel to ([Formula: see text]01) through O-H?F hydrogen bonds.

trans-Diaqua-bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole]cobalt(II) bis-(tetra-fluoridoborate).

Project description:The bidentate 1,3,4-thia-diazole ligand substituted by two 2-pyridyl rings (denoted L) has been found to produce the new monomeric title complex, [Co(C(12)H(8)N(4)S)(2)(H(2)O)(2)](BF(4))(2). The thia-diazole and pyridyl rings surrounding the Co atom are almost coplanar [dihedral angle = 4.35?(7)°]. The mean plane defined by these heterocyclic moieties makes a dihedral angle of 18.72?(6)° with the non-coordinated pyridyl ring. The Co(2+) cation, located at a crystallographic center of symmetry, is bonded to two ligands and two water mol-ecules in a trans configuration in an octa-hedral environment. The tetra-fluorido--borate ions can be regarded as free anions in the crystal lattice. Nevertheless, they are involved in an infinite two-dimensional network along the [010] and [101] directions of O-H?F hydrogen bonds.

Bis[2-(thio-phen-2-yl)quinoxaline-?N (4)]silver(I) tetra-fluoridoborate.

Project description:In the title compound, [Ag(C12H8N2S)2]BF4, the two-coordinate Ag(I) ion lies on a crystallographic inversion center and is linearly bonded to the N-donor atoms of two separate quinoxaline ligands. The thio-phenyl ring of the ligand is nearly coplanar with the quinoxaline ring system [dihedral angle = 9.15?(13)°]. In the crystal, the complex mol-ecules pack in layers parallel to (-102) and form weak ?-? ring stacking inter-actions [minimum ring centroid separation = 3.7054?(17)?Å]. The tetra-fluoridoroborate anion is equally disordered about an inversion center.

Bis[5-(pyridin-2-yl)pyrazine-2-carbo-nitrile-?N,N]silver(I) perchlorate.

Project description:In the mononuclear title complex, [Ag(C(10)H(6)N(4))(2)]ClO(4), the Ag(I) ion is surrounded by two 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands, forming a considerably distorted square-planar N(4)-coordination geometry, with two short and two long Ag-N distances. Each perchlorate anion links two mononuclear coordination units through C-H?O(perchlorate) hydrogen bonding, forming an infinite tape structure along [110]. Inter-molecular ?-? stacking inter-actions between adjacent pyridine and pyrazine rings [centroid-centroid distances of 3.777?(3) and 3.879?(2)?Å] further assemble the tape motifs into a three-dimensional supra-molecular structure.

(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.

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].

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: ?-? 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.

Tetra-aqua-bis-(2-{[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]sulfan-yl}acetato)-cobalt(II) monohydrate.

Project description:In the title compound, [Co(C(9)H(6)N(3)O(3)S)(2)(H(2)O)(4)]·H(2)O, the two 2-{[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]sulfan-yl}acetate ligands are monodentate. One coordinates the metal atom via the pyridyl N atom whereas the other coordinates via the carboxyl-ate O atom. The Co(II) atom adopts a slightly distorted octa-hedral coordination geometry with four O atoms of the coordinated water mol-ecules located in the equatorial plane and the N and O atoms of the two POA ligands in axial positions. In the crystal, the components are connected through O-H?O and O-H?N hydrogen bonds into a three-dimensional framework.

Project description:In the mononuclear title complex, [Ag(C(10)H(6)N(4))(2)]PF(6), two ?(2)N,N'-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the Ag(I) atom, forming a distorted N(4) tetra-hedral coordination geometry. The mononuclear units are inter-connected through ?-? inter-actions [centroid-centroid distances = 3.801?(2) and 3.979?(3)?Å] and the hexa-fluoridophosphate anions are embedded within the inter-stices. C N?? inter-actions [N?centroid = 3.519?(2)?Å] and C-H.?N hydrogen-bonding inter-actions also occur.
