The title compound, cyclo-tetrakis[(4-ethylpyridine-N)(N-salicylideneglycinato- O,N,O':O'')copper(II)], [Cu(C9H7NO3)(C7H9N)]4, adopts a square-pyramidal CuII coordination with the tridentate N-salicylideneglycinato Schiff base dianion (TSB2-) and the 4-ethylpyridine ligand bound in the basal plane. The apex of the pyramid is occupied by a carboxylic O atom from the neighbouring chelate at an apical distance of 2.458 (2) Å. Four such molecules build a tetrameric unit, in which all copper positions are magnetically nonequivalent. The unit cell contains four tetramers.
