Bis[N'-(3-cyanobenzylidene)isonicotinohydrazide-[kappa]N]silver(I) trifluoromethanesulfonate

Abstract top

In the title compound, [Ag(C14H10N4O)2]CF3SO3, two N atoms from two independent pyridyl rings of two N'-3-cyanobenzylideneisonicotinohydrazide ligands coordinate to the unique AgI ion, forming a nearly linear coordination geometry. Adjacent silver complexes are primarily linked together by Ag...N interactions, with Ag...N separations of 2.877 (2) and 3.314 (2) Å. On the other hand, one CF3SO3- anion interacts with hydrazone groups of two neighbouring ligands via N-H...O hydrogen bonds. These weak intermolecular interactions contribute to the formation of supramolecular chains. In addition, there are Ag...O interactions [2.787 (2) Å] between Ag and O atoms from adjacent chains.

Comment top

In the title compound, (I), the silver(I) ion is coordinated by two nitrogen atoms from two independent pyridyl rings of two different ligands, forming a slightly distorted linear coordination geometry (Fig. 1). Related bond distances and angle around the metal center are shown in Table 1.

There are N—H···O hydrogen bonds between hydrazone groups from 3-cyanobenzylidene isonicotinohydrazide and counteranions CF3SO3- (Table 2). Besides, there are weak Ag···N interactions between two neighbouring silver complexes with separations of 2.877 (2) and 3.314 (2) Å. Hydrogen bonds and Ag···N interactions link parallel silver monomers together to construct interesting supramolecular one-dimensional chains. Furthermore, two adjacent supramolecular one-dimensional chains are linked together via Ag···O interactions, with the separation of 2.787 (2) Å (Fig. 2). All these intermolecular interactions have the contribution to the three-dimensional structure of the title compound.

It is noteworthy that the coordination geometry of the silver metal center can be affected by many factors, such as coordination natures of organic ligands, temperature, counteranions, etc. (Dong et al., 2004; Niu et al., 2009; Sumby & Hardie, 2005; Abu-Youssef et al., 2007). We have reported a Ag(I) polymeric structure recently (Niu et al., 2008), which includes a ligand isomeric to the one used in this paper (3-cyanobenzylidene isonicotinohydrazide). It showed that the position of the CN functional group seems to have a great influence on the structures of the resulting compounds (monomeric versus polymeric).

Experimental top

A solution of AgCF3SO3 (0.026 g, 0.1 mmol) in CH3OH (10 ml) was carefully layered on a CH3OH/CHCl3 solution (5 ml/10 ml) of 3-cyanobenzylidene isonicotinohydrazide (0.025 g, 0.1 mmol) in a straight glass tube. About ten days later, colourless single crystals suitable for X-ray analysis were obtained.

Refinement top

C-bound H atoms were placed in calculated positions and refined using a riding model [C—H = 0.95 Å and Uiso(H) = 1.2Ueq(C)]. The N-bound H atoms were first introduced in calculated positions and refined freely with Uiso(H) = 1.2Ueq(carrier N). The final difference Fourier map had a highest peak at 0.76 Å from atom H24 and a deepest hole at 0.64 Å from atom S3, but was otherwise featureless.
