چکیده
The title compound, C(14)H(13)N(3)O(2), was prepared by the reaction of 2-methoxy-benzyaldehyde with nicotinic acid hydrazide in methanol. The dihedral angle between the benzene and pyridine rings is 5.9 (3)°. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds, leading to the formation of chains along the c axis; adjacent chains are linked via C-H⋯O and C-H⋯N hydrogen bonds.

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 t...
