A one-dimensional Ag coordination polymer: catena-poly[[[[N'-(4-cyano-benzyl-idene)nicotinohydrazide]silver(I)]-?-N'-(4-cyano-benzyl-idene)nicotino-hydrazide] trifluoro-methane-sulfonate].


ABSTRACT: 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.
