Abstract

The new ligands 1,9-bis(3,5-dimethyl-1-pyrazolyl)-2,5,8-trithianonane (L1) and 1,9-bis(benzinudazolyl)-2,5,8-trithianonane (L2) and their Cu(II) compleses as the BF 4 - , ClO 4 - , and CF 3 SO 3 - salts have been prepared. The X-ray structures of [Cu(L1)] [BF 4 ] 2 and [Cu(L3)] [CF 3 SO 3 ] 2 (L3=1,9-bis(2-pyridyl)-2,5,8-trithianonanc) have been determined. Crystal data for monoclinic [Cu(L1)] [BF 4 ] 2 : space group C2/c (No. 15); a=20.84(1) A, b=18.74(4) A, c=14.980(9) A; β=120.00(3) o ; Z=8; R=0.041, R w =0.073 for 2141 reflections
