metal-organic compounds
In the title chain compound, [Ag(NO3)(C3H7NO)(C26H24P2)]n, the bis(diphenylphosphino)ethane (dppe) components lie across centres of inversion. The dppe units link the Ag+ ions into chains along [100]. A nitrate anion is coordinated to the Ag atom, together with one molecule of N,N-dimethylformamide (DMF) solvent. At room temperature, the coordinated DMF shows a long Ag—O distance [2.620 (3) Å] and relatively large thermal motion, while at 100 K the Ag—O distance is shorter [2.5588 (19) Å] and the thermal motion is similar to that of the rest of the complex. The behaviour of the DMF molecule is related to the size of the solvent pocket, viz. 146 Å3 at 293 K and 131 Å3 at 100 K.
metal-organic compounds
The centrosymmetric title compound, [Ag(C7H4NO2S2)]n, consists of dinuclear units in which two thiosaccharinate anions each bridge two Ag atoms via an endocyclic N atom and an exocyclic S atom across a crystallographic centre of inversion midway between the Ag atoms. The dimeric units are connected via Ag—Sexo interactions to create two-dimensional networks. The thiosaccharinate anions bridge in a μ3-S:S:N manner. The AgAg distance can be considered a strong argentophilic interaction.
