catena-Poly
The two title compounds, [Cu(3)(C(6)H(11)O(2))(6)(C(7)H(9)N)(2)](n), (I), and [Cu(2)(C(5)H(9)O(2))(4)(C(7)H(9)N)(2)], (II), have chain and finite-molecular structures, respectively. In (I), binuclear cage units and mononuclear 2,6-dimethylpyridine complexes, both of which have inversion centres, are arranged alternately and are linked by the carboxylate ions to form one-dimensional chains along the a axis. In (II), the binuclear cage unit has an inversion centre and the coordination geometry around the Cu atom is typical square pyramidal, with 2,6-dimethylpyridine at the apical position.
