摘　　要：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=1.275 09（8） nm,b=1.275 09（8） nm,c=3.574 7（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[Cu2（ETU）6]+, in one of which the counter-ion SO2-4 is located.The ions with contrary charge,[Cu2（ETU）6]+ and SO2-4,are held together via the N—H…O hydrogen-bonded interactions resulting in a three-dimensional supramolecular network.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. 275 09（8） nm, b = 1.27：5 09（8） nm, c =3. 574 7（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 SO42- is located. The ions with contrary charge, [Cu（ETU） 3 ] ^＋ and SO4^2-, are held together via the N-H…O hydrogen-bonded interactions resulting in a three-dimensional supramolecular network.
