摘　　要：A new Co(II) coordination polymer bearing TTF carboxylate group, [{Co2(trioTTF)2(H2O)6}·5H2O]n (1) (trioTTF = 2-(5,6,8,9,11,12,14,15-octahydro-[1,3]dithiolo[4,5-h][1,4,13,7,10]trioxadithiacyclopentadecin-2-ylidene)-1,3-dithiole-4,5-dicarboxylate), has been prepared and characterized. In the structure of 1, shorter intermolecular S····S contacts (3.565 ?) are found between the trioTTF groups from neighboring chains. The electric conductivity of 1 is poor due to the bulky crown-ether group, but it exhibits ferromagnetic interaction at low temperature.A new Co(Ⅱ) coordination polymer bearing TTF carboxylate group, [{Co2(trioTTF)2(H2O)6}·5H2O]n (1) (trioTTF=2-(5,6,8,9,11,12,14,15-octahydro-[1,3]dithiolo[4,5-h][1,4,13,7,10]trioxadithiacyclopentadecin-2-ylidene)-1,3-dithiole-4,5-dicarboxylate), has been prepared and characterized.
