binuclear complexes with formula [M2(L-O,S)2] (M = CuII (1), NiII (2)) or [M2(L-O,S)3] (M = FeIII (4), CoIII (5)). In presence of dimethyl sulfoxide, [Mn2(L-O,S)2(dmso)2] (3) was successfully obtained and represents the first manganese complex with any thiourea derivative ligand. The ligand and the complexes were characterized by spectroscopic techniques and elemental analysis. Complexes 1, 3, 4 and
摘要 间苯二酰双(N,N-二苯基硫脲)分子(H2L 配体)与 CuI、CuII、MnIII、FeII、FeIII 和 CoII 离子反应形成双核配合物,分子式为 [M2(LO,S)2] (M = CuII (1 ), NiIII (2)) 或 [M2(LO,S)3] (M = FeIII (4), CoIII (5))。在二甲基亚砜的存在下,[Mn2(LO,S)2(dmso)2] (3) 被成功获得,并且代表了第一个与任何硫脲衍生物配体的锰配合物。配体和配合物通过光谱技术和元素分析表征。通过单晶 X 射线衍射数据对配合物 1、3、4 和 5 进行结构分析,证实了 O,S 螯合配位模式。通过形成相应金属氧化物的热分析证实了化学计量。
