Crystal structures of the heterometallic complex [Co · 15-crown-5 · (CH3CN)2][Cu2Cl6] and the product of its hydration [Co · 15-crown-5 · (H2O)2][CuCl4]
摘要:
Interaction of anhydrous CoCl2 and CuCl2 with 15C5 in acetonitrile gave the ionic complex [Co.15C5.(CH3CN)2][Cu2Cl6] (I) with the cobalt atom located in the inner cavity of the macrocycle. Thermal decomposition of I starts at 140-degrees-C with the dissociation of the acetonitrile to finally produce CoCl2 and CuCl. Hydration of I gave a mixture of CuCl2.2H2O and [Co.15C5.(H2O)2][CuCl4] (IV). Cobalt is also located in the inner cavity in IV and has a coordination number of 7.
