The title compound, bis­[μ-3-ethyl-5-(pyridin-2-yl)-1H-1,2,4-triazol-1-ido]bis[acetato­(di­methyl­formamide)­copper(II)], [Cu2(C9H9N4)2(C2H3O2)2(C3H7NO)2] or [Cu2(LEt)2(OAc)2(dmf)2], is a triazolate complex, which contains two 3-(2-pyrid­yl)-5-ethyl-triazolates (LEt) in bidentate-bridged coordination modes. Both copper atoms are involved in the formation of a planar six-membered metallocycle Cu–[N—N]2–Cu. The inversion center of the complex is located at the mid-point of the Cu⋯Cu vector. Each CuII atom has a distorted trigonal–bipyramidal environment formed by the three nitro­gen atoms of the deprotonated bridging 3-(2-pyrid­yl)-5-ethyl-triazolate unit, oxygen atoms of the OAc group and dmf mol­ecule. In the crystal, C—H⋯O hydrogen bonds link the mol­ecules into chains running along the c-axis direction.
