ABSTRACT
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 [Oâ¯O = 2.660â (2)â Å]. The mol-ecular packing forms a puckered pseudo-hexa-gonal close-packed layer in the (h00) plane, with soft inter-molecular Hâ¯H contacts (2.46-2.58â Å).
ABSTRACT
The molecule of the title compound, [Cu(2)(C(9)H(9)O(2))(4)(C(9)H(10)O(2))(2)], lies on a center of inversion. It consists of four bridging ethyl-benzoate ligands, forming a cage around two Cu atoms in a syn-syn configuration, and two monodentate ethyl-benzoic acid ligands bonded apically to the square-planar Cu atoms. The Cuâ¯Cu distance is 2.6047â (5)â Å.
