Herein, we communicate the formation of novel ruthenium compounds with N, X-donor (X = O, N) heterocyclic- derived ligands. A paramagnetic ruthenium(IV) complex, [RuCl(pho)(bzca)(PPh3)](1) (pho = 2- aminophenolate; bzca = 2-carboxylate-1H-benzimidazole) was isolated from the reaction of the ruthenium(II) precursor, trans-[RuCl2(PPh3)3] and 2-((1H-benzimidazole)methylamino)phenol (Hbzap). The 1:1 molar
在本文中,我们传达了具有N,X供体(X = O,N)杂环衍生的配体的新型钌化合物的形成。从钌(II)的反应中分离出顺磁性钌(IV)络合物[RuCl(pho)(bzca)(PPh3)](1)(pho = 2-氨基酚盐; bzca = 2-羧酸盐-1H-苯并咪唑) )前体,反式[RuCl2(PPh3)3]和2-((1H-苯并咪唑)甲基氨基)苯酚(Hbzap)。同一金属前体与N-(苯并恶唑)-2-羟基苯甲酰胺(H2bhb)的1:1摩尔反应导致形成顺式-Cl,反式-P- [RuIII(Hbhb)Cl2(PPh3)2](2 )。双核钌化合物(l-Htba,Cl)2 [RuIICl(PPh3)] 2(3)(Htba = N-(噻吩)甲基-苯并恶唑-2-胺)和(1-Cl)2 [RuIIICl(Hchpr)(PPh3)] 2(4)(由反式-[RuCl2(PPh3)3]与各自的等摩尔比配位反应形成H2chpr
