摘要

The reaction of CuSO4 center dot H2O with 4-bpytm [4-bpytm = bis(4-pyridylthio)methane] in EtOH afforded the complex [Cu(SO4)(4-bpytm)(H2O)(3)]center dot H2O (1 center dot H2O) while the reaction of 4-bpytm with Cu(NO3)(2)center dot 3H(2)O in EtOH afforded the complex [Cu(NO3)(2)(4-bpytm)(2)]center dot H2O (2 center dot H2O). The reaction of 4-bpytm with Cu(NO3)(2)-3H(2)O in EtOH/dmf under microwave irradiation afforded the pseudo-polymorph [Cu(NO3)(2)(4-bpytm)2]center dot Solv (2.Solv). Compound 1 center dot H2O forms helical chains while compounds 2 center dot H2O and 2.Solv are 2D coordination polymers with a (4,4) topology based on rhombic grids in 2 center dot H2O and on a parquet motif in 2.Solv. The 3D supramolecular organization through hydrogen bonding is analyzed for the three compounds and their thermal behaviour was also investigated. (C) 2008 Elsevier Ltd. All rights reserved.
