The title compound, {(C6H8N)[AgWSe4]·C6H7N}n, consists of anionic [WAgSe4]n chains, 2-methylpyridinium cations and neutral 2-methylpyridine molecules. The Se atoms bridge the Ag and W atoms, forming a polymeric chain extending along the b-axis direction. Both the Ag and W atoms are located on a twofold rotation axis and each metal atom is coordinated by four Se atoms in distorted tetrahedral geometry. In the crystal, the 2-methylpyridinium cation and 2-methylpyridine molecule are linked via N—HN hydrogen bonding. Weak C—HSe interactions link the organic components and polymeric anions into a three-dimensional architecture.

The title compound, C4H6ClNO3, crystallizes with two independent molecules (A and B) in the asymmetric unit. In each molecule, there are N—HO and N—HCl hydrogen bonds. Both molecules are relatively planar, with the mean plane of the acetamide [N—C(=O)C] group being inclined to the mean plane of the acetate group [C—C(=O)O] by 9.23 (13)° in molecule A and 6.23 (12)° in molecule B. In the crystal, adjacent molecules are linked by O—HO hydrogen bonds and weak C—HO contacts forming –A–A–A– and –B–B–B– parallel chains propagating along the a-axis direction.
