A new [Cu(ox)(Im)2] complex resulting from the oxidation of chelidonate to oxalate

We report herein the solid state structure of a new complex [Cu(ox)(Im)2] (II) which adopts a mononuclear 0D form in contrast to the polymeric 1D form adopted by the previously described [ Cu ( ox ) ( Im ) 2 ] ∞ 1 (I). Both compounds were obtained from an oxidative transformation of chelidonate to oxalate in the presence of Cu(II) and imidazole. The packing and weak interactions of II are analyzed and compared with those of I.
