Crystal Structure of Sodium O,O'-Nitritonitroargentate(I)

Abstract

The crystal structure of the title compound, NaAg(NO₂)₂, has been determined by single-crystal X-ray diffraction at 295(1) K and refined by full-matrix least squares to a residual of 0.043 for 449 'observed' reflections. Crystals are orthorhombic, space group Fd2d, a 7.913(2), b 10.721(2), c 10.857(3) Å, Z 8. The structure is closely related to that of sodium and silver nitrites; the silver environment is dominated by the 'linear' coordination of a nitro group (Ag-N 2.25(2) Å) and a 'chelating' pair of oxygen atoms from another NO₂- species (Ag-O 2.422(8)Å), the O₂N-Ag-O₂N group containing a crystallographic 2 axis.
