چکیده
In the title centrosymmetric dinuclear compound, [Cu(2)(C(8)H(7)O(2))(4)(C(8)H(8)O(2))(2)], four o-toluate anions form a cage around two Cu atoms in a syn-syn configuration. Two more o-toluic acid mol-ecules are apically bonded to the Cu atoms, which show a square-pyramidal coordination geometry. The acid H atoms are hydrogen bonded to the cage carboxyl O atoms [O⋯O = 2.660 (2) Å]. The mol-ecular packing forms a puckered pseudo-hexa-gonal close-packed layer in the (h00) plane, with soft inter-molecular H⋯H contacts (2.46-2.58 Å).
