K. Cheng, R.-Z. Hu and L. Ai

Abstract: The orthorhombic (space group Pna2₁) title compound, [Ag(C₇H₆NO₂)]_n, is a polymorph of the known monoclinic (P2₁/n) variant of this stoichiometry [Smith, Lynch & Kennard (1999). Aust. J. Chem. 52, 325-327]. In the title compound, the Ag atom shows linear coordination to one O and one N atom [Ag-O = 2.138 (5) Å, Ag-N = 2.153 (4) Å and O-Ag-N = 173.55 (18)°]. In the monoclinic form, the Ag coordination to two O atoms and one N atom can be described as Y-shaped or distorted trigonal planar. Weak AgAg interactions, aromatic - stacking and N-HO hydrogen-bond interactions help to establish the crystal packing in the title compound.
