Bis[N'-(3-cyano-benzyl-idene)isonicotino-hydrazide]silver(I) trifluoro-acetate.

ABSTRACT: In the title compound, [Ag(C(14)H(10)N(4)O)(2)]CF(3)CO(2), the Ag(I) ion is coordinated by two N atoms of the pyridine rings of two N'-(3-cyano-benzyl-idene)isonicotinohydrazide ligands in a nearly linear geometry. In the crystal structure, a combination of close contacts formed via Ag?N inter-actions [Ag?N = 3.098?(2) and 3.261?(2)?Å] from symmetry-related mol-ecules and inter-molecular N-H?O hydrogen bonds between CF(3)CO(2) (-) anions and the hydrazone groups of two ligands give rise to chains. Furthermore, there are Ag?O inter-actions with a separation of 2.765?(2)?Å between chains. The F atoms of the CF(3)CO(2) (-) anion are disordered over two sites with refined occupancies of 0.593?(5) and 0.407?(5).

In the title compound, [Ag(C(14)H(10)N(4)O)(2)]CF(3)CO(2), the Ag(I) ion is coordinated by two N atoms of the pyridine rings of two N'-(3-cyano-benzyl-idene)isonicotinohydrazide ligands in a nearly linear geometry. In the crystal structure, a combination of close contacts formed via Ag⋯N inter-actions [Ag⋯N = 3.098 (2) and 3.261 (2) Å] from symmetry-related mol-ecules and inter-molecular N-H⋯O hydrogen bonds between CF(3)CO(2) (-) anions and the hydrazone groups of two ligands give rise to chain ...[more]

Project description:In the title compound, [Ag(C(14)H(10)N(4)O)(2)]CF(3)SO(3), two N atoms from two independent pyridyl rings of two N'-3-cyano-benzyl-ideneisonicotinohydrazide ligands coordinate to the unique Ag(I) ion, forming a nearly linear coordination geometry. Adjacent silver complexes are primarily linked together by Ag?N inter-actions, with Ag?N separations of 2.877?(2) and 3.314?(2)?Å. On the other hand, one CF(3)SO(3) (-) anion inter-acts with hydrazone groups of two neighbouring ligands via N-H?O hydrogen bonds. These weak inter-molecular inter-actions contribute to the formation of supra-molecular chains. In addition, there are Ag?O inter-actions [2.787?(2)?Å] between Ag and O atoms from adjacent chains.

Project description:The title compound, C(13)H(10)BrN(3)O, was prepared by the reaction of isonicotinohydrazide and 4-bromo-benzaldehyde.

Project description:In the title compound, {[Ag(C(14)H(10)N(4)O)(2)]CF(3)SO(3)}(n), the unique Ag(I) ion is coordinated by two N atoms from two pyridine rings of two independent N'-(4-cyano-benzyl-idene)nicotinohydrazide ligands and one N atom of a carbonitrile group of a symmetry-related N'-(4-cyano-benzyl-idene)nicotino-hydrazide ligand, forming a distorted T-shaped coordination environment. One of the independent ligands acts as a bridge connecting Ag(I) ions, forming chains along the a axis. In the crystal structure, two neighbouring anti-parallel chains are connected through N-H?O hydrogen bonds. In addition, there are relatively short Ag?O contacts of 2.723?(3)?Å, which connect the chains into a three-dimensional structure.

Project description:In the title compound, {[Ag(C(14)H(10)N(4)O)(2)]AsF(6)}(n), the Ag(I) ion is coordinated by two N atoms from two different pyridyl rings and one N atom from one carbonitrile group of three different N'-(4-cyano-benzyl-idene)nicotinohydrazide ligands in a distorted T-shaped geometry. The Ag-N(carbonitrile) bond distance is significant longer than those of Ag-N(pyrid-yl). The bond angles around the Ag(I) atom are also not in line with those in an ideal T-shaped geometry. One type of ligand acts as the bridge that connects Ag(I) atoms into chains along [01]. These chains are linked to each other via N-H?O hydrogen bonds and Ag?O inter-actions with an Ag?O separation of 2.869?(2)?Å. In addition, the [AsF(6)](-) counter-anions are linked to the hydrazone groups through N-H?F hydrogen bonds. Four of the F atoms of the [AsF(6)](-) anion are disordered over two sets of sites with occupancies of 0.732?(9) and 0.268?(9).

Project description:In the title complex, {[Ag(2)(CF(3)O(3)S)(2)(C(30)H(20)N(6))]·C(6)H(6)}(n), the two independent Ag(I) ions are each coordinated by two N atoms and one O atom in a 'T-shaped' geometry. In the crystal structure, 1,2-bis-[(3-cyano-benzyl-idene)hydrazono]-1,2-diphenyl-ethane ligands act as bridging ligands and each coordinates to four Ag(I) ions, resulting in a one-dimensional chain structure. The crystal structure is stabilized by weak inter-molecular C-H?O hydrogen bonds.

Project description:In the title polymer, {[Ag(C(14)H(10)N(4)O)(2)]PF(6)}(n), each Ag(I) ion is coordinated by two N atoms from two pyridyl rings of independent N'-(4-cyano-benzyl-idene)nicotinohydrazide ligands, and one N atom from one carbonitrile group of a symmetry-related ligand in a distorted T-shaped geometry. The ligands exhibit two modes of coordination. One acts as a bridge connecting Ag atoms to form one-dimensional chains along [01]. The other acts as a terminal monodentate ligand, coordinating to Ag through its pyridyl N atom. Two neighbouring anti-parallel chains in the crystal are connected through N-H⋯O hydrogen bonds. Other adjacent chains are packed via Ag⋯O inter-actions, with Ag⋯O separations of 2.876 (2) Å. In addition, PF(6) (-) counter-anions inter-act with the hydrazone groups through N-H⋯F hydrogen bonds. The PF(6) (-) anion is disordered over two sites, with occupancies of 0.773 (8) and 0.227 (8).
