catena-Poly[[(5-ethyl-2-methylpyridine-N)copper(II)]-[mu]-(N-salicylideneglycinato-O,N,O':O'')]

The title complex, [Cu(C₉H₇NO₃)(C₈H₁₁N)]_n, adopts a square-pyramidal Cu^II coordination with the tridentate N-salicylideneglycinato Schiff base dianion (TSB^2-) 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.
