phenol ligand 2-(bis(2-pyridylmethyl)aminomethyl)-6-((2-pyridylmethyl)(benzyl)aminomethyl)-4-me thylphenol with Mn(OAc)(2).4H(2)O or Mn(H(2)O)(6)(ClO(4))(2) in the presence of NaOBz affords the dimanganese(II) complexes 1(CH(3)OH), [Mn(2)(L)(OAc)(2)(CH(3)OH)](ClO(4)), and 2(H(2)O), [Mn(2)(L)(OBz)(2)(H(2)O)](ClO(4)), respectively. On the other hand, reaction of the ligand with hydrated manganese(III)
不对称酚配体2-(双(2-吡啶基甲基)氨基甲基)-6-((2-吡啶基甲基)(苄基)氨基甲基)-4-甲基苯酚与Mn(OAc)(2).4H(2)O的反应或在NaOBz存在下Mn(H(2)O)(6)(ClO(4))(2)提供二锰(II)配合物1(CH(3)OH),[Mn(2)(L) (OAc)(2)(CH(3)OH)](ClO(4))和2(H(2)O),[Mn(2)(L)(OBz)(2)(H(2) O)](ClO(4))。另一方面,配体与水合乙酸锰(III)的反应提供了混合价衍生物3(H(2)O),[Mn(2)(L)(OAc)(2)(H(2) O)](ClO(4))(2)。三种配合物已经通过X射线晶体学表征。1(CH(3)OH)在单斜晶系空间群P2(1)/ c中结晶,a = 10.9215(6)A,b = 20.2318(12)A,c = 19.1354(12)A,alpha = 90度,beta
