Abstract top

In the centrosymmetric dinuclear title AgI compound, [Ag2(C6H6N2O)4](NO3)2, the aromatic amine-coordinated AgI atom is further bridged by two hydroxylamine molecules that use aromatic and oxime N atoms for bridging, and it exists in a distorted trigonal-planar geometry. In the crystal, the nitrate anions link to the dinuclear compound molecules via O-H...O hydrogen bonds, generating a chain running along the a-axis direction.

Comment top

A previous study on the adducts of silver salts with nicotinylaldehyde oxime reported the salt, [Ag(C6H6N2O)2] ClO4; the metal atom shows linear coordination (Xu et al., 2012). The aromatic amine-coordinated AgI atom in dinuclear [Ag(C6H6N2O)2]2 2NO3 is bridged by another hydroxylamine molecule that uses its aromatic and oxime N atoms for bridging, and it exists in a trigonal planar geometry (Scheme I, Fig. 1). The hydroxyl OH groups forms H atoms to the nitrate O atoms of adjacent molecules to generate a chain running along the shortest axis of the orthorhombic unit cell (Table 1).

With picolinylaldehyde oxime in place of nicotinylaldehyde oxime, the synthesis yields the monomeric adduct in which the metal atom is chelated by the ligand (Abu-Youssef et al., 2010).

Experimental top

Nicotinyladehyde oxime was synthesized from the reaction of nicotinylaldehyde and hydroxylamine. Silver nitrate (1 mmol) dissolved in water (5 ml) was added to nicotinylaldehyde oxime (1 mmol) dissolved in ethanol (5 ml). The solution was filtered and set aside, away from light, for the growth of colorless crystals.

Refinement top

Carbon- and oxygen-bound H-atoms were placed in calculated positions (C–H 0.93 Å, O–H 0.84 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2–1.5U(C,O).

The (-1 3 3), (5 - 10 1), (6 - 9 5) and (0 9 1) reflections were omitted.

The final difference Fourier map had a peak at 0.88 Å from Ag1.
