Thiophene-2-thiocarboxylate complexes of Cu(I), [(Ph3P)2Cu(SCOth)] (1) and H[(Ph3P)2Cu(SCOth)2] (2) (where th = thiophene) were synthesized and characterized structurally by X-ray crystallography. Electronic absorption and emission spectral properties of the two compounds have been studied. Cu(II) complexes, [(TMEDA)Cu(SCOth)2] (3b) and [(Phen)Cu(SCOth)2] (4a) (where TMEDA = tetramethylethylenediamine; Phen = 1,10-phenanthroline) were prepared and characterized by spectroscopic measurements. 3b and 4a underwent desulfurization under ambient conditions readily yielding the corresponding carboxylate complexes [(TMEDA)Cu(O2Cth)2] (3a) and [(Phen)Cu(O2Cth)2·H2O] (4b). 3a and 4b have been characterized crystallographically.
合成并通过X射线晶体学对Cu(I)的
噻吩-2-
硫羧酸酯配合物[(Ph3P)2Cu(SCOth)] (1)和H[(Ph3P)2Cu(SCOth)2] (2)进行了结构表征(其中th =
噻吩)。研究了这两种化合物的电子吸收和发射光谱特性。还制备了Cu(II)配合物[(TME
DA)Cu(SCOth)2] (3b)和[(Phen)Cu(SCOth)2] (4a)(其中TME
DA =
四甲基乙二胺;Phen = 1,10-
菲啰啉),并通过光谱测量进行了表征。在常温条件下,3b和4a易于脱
硫,生成相应的
羧酸盐配合物[(TME
DA)Cu(O2Cth)2] (3a)和[(Phen)Cu(O2Cth)2·H2O] (4b)。3a和4b已通过晶体学进行了表征。
