The title complex, [Cu(C9H7NO3)(C8H11N)]n, adopts a square-pyramidal CuII coordination with the tridentate N-salicylideneglycinato Schiff base dianion (TSB2-) and the 5-ethyl-2-methylpyridine ligand bound in the basal plane. The apex of the pyramid is occupied by the carboxylic O atom from the neighbouring chelate at an apical distance of 2.268 (2) Å, which is the shortest apical distance in this class of substances.
