The urea group and the benzene ring are nearly coplanar, the dihedral angle between them being 4.15?(7)°. The crystal packing is stabilized by aromatic ?-? stacking inter-actions, with a centroid-to-centroid separation of 3.833?(4)?Å.

The mol-ecule of the title compound, C(17)H(10)N(4)O, has crystallographically imposed C(2) symmetry. The urea group and the benzene ring are nearly coplanar, the dihedral angle between them being 4.15 (7)°. The crystal packing is stabilized by aromatic π-π stacking inter-actions, with a centroid-to-centroid separation of 3.833 (4) Å. ...[more]

Project description: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).

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).

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

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: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).

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:The title Schiff base compound, C(14)H(10)Cl(2)N(2), crystallizes with one half-mol-ecule in the asymmetric unit.
