摘要：
Two cobalt(II) coordination polymers formed from bte (bte = 1,2-bis(1,2,4-triazol-1-yl)ethane), namely [Co(bte)(2)(dca)(2)]n (1) and {[Co(bte)(dca)(2)]center dot H2O}n (2), have been synthesized and characterized by elementary analyses, IR, thermogravimetric analyses, X-ray diffraction analyses and magnetic measurements. Compound 1 is a double-chain with Co(II) centers bridged by bte, containing metallocycles of [Co-2(bte)(2)] and trans dca as termination ligands. In 2, each Co(II) center is bonded by two bridging bte ligands and four dca as mu-1,5-dca in different orientations in the 3D network. (C) 2007 Elsevier Ltd. All rights reserved.
