摘要

The hydrothermal reaction of Co(CH_3COO)_2 centre dot 4H_2O,NaVO_3,2,2'-dipyridylamine(dpaH)and H_2O yielded a novel crystal [Co_4O_4(dpaH)_4(CH_3COO)_2]_2V_4O_(12)centre dot 5H_2O,which was characterized by X-ray structure analysis.The crystal structure is composed of an isolated molecular unit [V_4O_(12)]~(4-)and two [Co_4O_4(dpaH)_4(CH_3COO)_2]~(2+)moieties.The cobalt atoms and the bridging-oxygen atoms are introduced as structure-directing components and form the [Co_4O_4] cubane core.As the N-Co-N bond angles increase,the O-Co-O bond angles of the acetate-bridged top and bottom faces decrease and the four-membered cobalt-oxygen rings are more distorted.
