The synthesis, structural, and spectroscopic characterization of four new coordinatively unsaturated mononuclear thiolate-ligated manganese(II) complexes ([MnII(SMe2N4(6-Me-DPEN))](BF4) (1), [MnII(SMe2N4(6-Me-DPPN))](BPh4)·MeCN (3), [MnII(SMe2N4(2-QuinoPN))](PF6)·MeCN·Et2O (4), and [MnII(SMe2N4(6-H-DPEN)(MeOH)](BPh4) (5)) is described, along with their magnetic, redox, and reactivity properties. These
四种新型配位不饱和单核硫醇连接锰 (II) 配合物 ([Mn II (S Me2 N 4 (6-Me-DPEN))](BF 4 ) ( 1 ), [Mn II (S Me2 N 4 (6-Me-DPPN))](BPh 4 )·MeCN ( 3 ), [Mn II (S Me2 N 4 (2-QuinoPN))](PF 6 )·MeCN·Et 2 O ( 4 ) 和 [Mn II (S Me2 N 4 (6-H-DPEN)(MeOH)](BPh 4 ) (5 )) 以及它们的磁性、氧化还原和反应性特性。这些复合物在结构上与最近报道的 [Mn II (S Me2 N 4 (2-QuinoEN))](PF 6 ) ( 2 ) (Coggins, MK; Kovacs, JA J. Am. Chem. Soc. 2011 , 133 , 12470)。复合物1 – 5的双氧加成导致形成五个新的稀有实例
