The synthesis and characterization of ruthenium(II) complexes, [RuCl2(dmso)2(bfmh)] (1; dmso = dimethyl sulfoxide, bfmh = benzoic acid furan-2-ylmethylene-hydrazide), [RuCl2(dmso)2(btmh)](2; btmh = benzoic acid thiophen-2-ylmethylene-hydrazide), [RuCl2(dmso)2(bfeh)](3; bfeh = benzoic acid (1-furan-2-yl-ethylidene)-hydrazide) and [RuCl2(dmso)2(bpeh)](4; bpeh = benzoic acid (1-pyridin-2-yl-ethylidene)-hydrazide)
钌(II)配合物[RuCl 2(dmso)2(bfmh)](1 ; dmso =二甲基亚砜,bfmh =苯甲酸呋喃-2-基亚甲基酰肼),[RuCl 2(dmso)2(btmh)](2 ; btmh =苯甲酸噻吩-2-基亚甲基酰肼),[RuCl 2(dmso)2(bfeh)](3 ; bfeh =苯甲酸(1-呋喃-2-基-亚乙基)-描述了[RuCl 2(dmso)2(bpeh)](4; bpeh =苯甲酸(1-吡啶-2-基-亚乙基)-酰肼)。配体,当用任一顺式-[RuCl 2(dmso)处理时4 ]或反式(Cl)– [RuCl 2(dmso)2(bpy)],则产生相同的产品。红外光谱和单晶X射线衍射研究已证实了这一点。已经发现配合物的氧化还原行为强烈地取决于present配体中存在的部分的电子性质。已经通过吸收滴定和循环伏安法研究了复合物与鲱鱼精子DNA的结合。但是,由于添加DNA时吸收的随
