In the interaction of norzooanemonin 1,3-dimethylimidazolium-4-carboxylate (1) with CuBr2, two types of crystals form: purple [Cu(L)2Br2][CuBr4][CuL4] (2) and light blue [CuL4][CuBr3] (3). In the reaction of 1 with CoCl2 in methanol, neutral complex Co(L)2Cl2 (4) forms. The thermal decomposition of complex 4 is studied. At the first stage of this decomposition, two equivalents of CO2 remove in a range 218–275 °C, and then a two-phase removal of two equivalents of L and the formation of CoCl2 occur.
