摘要： 选用具有丰富配位模式(单齿、二齿或三齿)的亚乙基硫脲(ETU, 代森类杀菌剂的有毒降解物, 通过和金属离子配位有可能使其性状发生改变)作配体, 在溶剂热条件下合成出一种由氢键构筑的、新的三维超分子配位聚合物[Cu2(ETU)6]SO4(1), 并对其结构进行了详细表征.

Abstract: A novel coordination polymers [Cu2(ETU)6]SO4(1)(ETU=ethylidene thiourea) was synthesized under solvothermal conditions. The crystal structure of the polymer was determined by X-ray diffraction: trigonal, space group R3c(No. 161), a=1.27509(8) nm, b=1.27509(8) nm, c=3.5747(7) nm, γ=120°, Z＝6, CCDC Number: 605501. In the structure of the polymer, each metal ion Cu(Ⅰ) coordinates to three S atoms attached to the ring of ETU forming two triangular pinwheel-shape monovalent cations [Cu(ETU)3]+, in one of which the counter-ion SO2-4 is located. The ions with contrary charge, [Cu(ETU)3]+ and SO2-4, are held together via the N—H…O hydrogen-bonded interactions resulting in a three-dimensional supramolecular network.

Key words: Solvothermal synthesis, Supramolecular network, Hydrogen-bond, Ethylidene thiourea
