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

ABSTRACT: 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.

Bis[5-(pyridin-2-yl)pyrazine-2-carbo-nitrile-κ(2)N(4),N(5)](trifluoro-acetato-κO)silver(I).

Project description:In the asymmetric unit of the title compound, [Ag(C(10)H(6)N(4))(2)(CF(3)CO(2))], there two mononuclear but slightly different complex units. In each, two κ(2)N:N-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the Ag(I) atom, giving an N(4)O square-pyramidal coordination geometry with one trifluoro-acetate O atom at the apex. The difference between the two lies in the Ag-N bond lengths: in one complex, three normal [range 2.272 (5)-2.552 (5) Å] and one long [2.706 (4) Å] and in the second, two normal [2.254 (5) and 2.290 (5) Å] and two long [2.647 (5) and 2.675 (5) Å] are present. Short inter-molecular F⋯F contacts [2.586 (4) Å] and weak π-π stacking inter-actions [minimum ring centroid separation 3.836 (5) Å] between pyridyl and pyrazinyl rings connect the complex units, forming columns which extend along the b-axis direction.

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.

(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.

Di-aqua-bis-[5-(2-pyrazin-2-yl)tetra-zolato]copper(II)-pyrazine-2-carbo-nitrile (1/2).

Project description:The title compound, [Cu(C5H3N6)2(H2O)2]·2C5H3N3, is a 1:2 co-crystal between the mononuclear complex di-aqua-bis-[5-(pyrazin-2-yl)tetra-zolato]copper(II) and the reagent pyrazine-2-carbo-nitrile which was used in the synthesis. The Cu(II) atom is located on an inversion centre and has a distorted octa-hedral [4 + 2]-coordination environment formed by four N atoms of two chelating bidentate 5-(pyrazin-2-yl)tetra-zolate ligands at shorter distances and two water O atoms at longer distances. The Cu(II) complex molecules are held together by O-H⋯N hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance 3.6139 (8) Å], forming layers parallel to (100). These layers alternate with layers of pyrazine-2-car-bo-nitrile mol-ecules and both are held together via C-H⋯N hydrogen bonds and further π-π stacking inter-actions.

Bis[?-1-(3,5-di-chloro-pyridin-2-yl)-2-(pyridin-3-yl-methyl-idene)hydrazine]bis-[(nitrato-?O)silver(I)] aceto-nitrile disolvate.

Project description:In the centrosymmetric binuclear title complex, [Ag2(NO3)2(C11H8Cl2N4)2]·2CH3CN, the Ag(I) atom is four-coordinated and exhibits a highly distorted tetrahedral coordination sphere defined by three N atoms from two 1-(3,5-di-chloro-pyridin-2-yl)-2-(pyridin-3-yl-methyl-idene)hy-drazine ligands and one O atom from a nitrate anion. Inter-molecular N-H?O hydrogen bonds link the complex mol-ecules, resulting in a two-dimensional supra-molecular structure parallel to (001).

Bis[(E)-N-(pyridin-3-yl-methyl-idene)hydroxyl-amine-?N(1)]silver(I) perchlorate.

Project description:Each of the ions in the title salt, [Ag(C(6)H(6)N(2)O)(2)]ClO(4), is completed by the application of crystallographic twofold symmetry. The Ag(I) atom is coordinated by two pyridine N atoms in an almost linear fashion [N-Ag-N = 170.0?(2)°], with the T-shaped coordination geometry being completed by a weakly associated perchlorate-O atom. Supra-molecular zigzag chains along [100] mediated by O-H?N hydrogen bonds [as parts of R(2) (2)(6) loops] feature in the crystal packing. The perchlorate O atoms are disordered over two sets of sites in a statistical ratio.

trans-Tetra-aqua-bis-[bis-(pyridin-3-yl)methanone-?N]manganese(II) bis-(perchlorate).

Project description:In the title complex, [Mn(C(11)H(8)N(2)O)(2)(H(2)O)(4)](ClO(4))(2), the Mn(2+) ion is located on an inversion center with the slightly distorted N(2)O(4) octa-hedral coordination sphere comprising N-atom donors from two monodentate trans-related bis-(pyridin-3-yl)methanone ligands and four water ligands. The two perchlorate anions are linked to the mononuclear complex mol-ecule through water O-H?O hydrogen bonds while inter-complex water O-H?N(pyridine) inter-actions form an infinite chain structure extending along the b axis. The perchlorate anions also function as inter-unit links through water O-H?O hydrogen bonds which, together with water O-H?O(carbon-yl) inter-actions, give a three-dimensional framework structure.

{1,1'-Bis[(pyridin-2-yl)meth-yl]-2,2'-bipiperid-yl}(perchlorato)copper(II) perchlorate.

Project description:The title complex, [CuII(ClO4)(mesoPYBP)](ClO4) {PYBP = 1,1'-bis-[(pyridin-2-yl)meth-yl]-2,2'-bipiperidyl, C22H30N4}, was prepared and found to crystallize with two crystallographically independent complex salt moieties. The metal atoms of the cations adopt a pseudo-square-pyramidal coordination geometry, where the tetra-dentate amino-pyridine ligands (PYBP) are wrapped around the Cu atoms in the equatorial plane. The Cu-O bonds involving an O atom of the coordinating perchlorate anion are approximately perpendicular to the plane. The two remaining non-coordinating perchlorate anions are involved in several C-H?O hydrogen bonds with the PYBP ligand and balance the total charge of the complex salt. The two crystallographically independent moieties are related to each other via a pseudo-translation along the a-axis direction. Exact translational symmetry is broken by (i) a difference in the conformation of one of the piperidine rings, featuring a chair conformation in one of the cations, and a sterically disfavored boat conformation in the other; and (ii) by modulation of the non-coordinating perchlorate anions.

Bis[(2-methyl-benz-yl)bis-(pyridin-2-ylmethyl-κN)amine-κN]manganese(II) bis-(perchlorate).

Project description:In the title complex, [Mn(C20H21N3)2](ClO4)2, two tridentate (2-methyl-benz-yl)bis-(pyridin-2-ylmeth-yl)amine (L) ligands form the Mn(II) complex [MnL 2](ClO4)2. The Mn(II) ion lies on a twofold axis and the complex cation is significantly distorted from regular octa-hedral geometry. The packing is stabilized by weak C-H⋯O inter-actions between the cations and anions, which link them into a zigzag ribbon along [101]. The perchlorate anion is disordered and was constrained to be tetra-hedral with two orientations having occupancies of 0.768 (4) and 0.232 (4). The 2-methylbenzyl moiety is also disordered over two sets of sites, with occupancies of 0.508 (15) and 0.492 (15).
