It is a challenge to design and synthesize coordination polymers with high capacities as anode materials in Li-ion batteries at present. In this work, two compounds [Co-2(ade)(2)(V4O12)(H2O)(2)] (1) and [Cd-2(ade)(2)(V4O12)(H2O)(2)] (2) (ade = adenine) with high capacities have been successfully obtained through the sensible design strategy. In compounds 1 and 2, Co(II) and Cd(II) are linked by [V4O12](4-) anion to form 2D inorganic layers which are further connected to generate final 3D frameworks. Both compounds I and 2 show good thermal stability according to the thermogravimetric analyses. The electrochemical performances of the two compounds as anode materials have been studied in detail. The results show compounds 1 and 2 have high reversible capacities and cyclic performances in Li-ion batteries.
