4-(4-formyl-5-oxo-3-methyl-pyrazol-1-yl)-benzenesulfonic acid and o-phenylenediamine or ethylenediamine. And these are characterized by elemental analysis, FT-IR, (1)H NMR and GC-MS. The corresponding Schiff base complexes of Mn(III) were prepared by condensation of [Mn(3)(mu(3)-O)(OAc)(6)(H(2)O)(3)].3H(2)O with ligands H(2)L(1), H(2)L(2), H(2)L(3) and H(2)L(4). All these complexes have been characterized by
席夫碱四齿配体N,N-双-(3,5-二甲基-1-对甲苯基-1H-吡唑-4-基亚甲基)-乙烷-1,2-二胺(H(2)L(1)) ,N,N-双-(3,5-二甲基-1-对磺酰基-1H-吡唑-4-基亚甲基)乙烷-1,2-二胺(H(2)L(2)),N,N -双-(3,5-二甲基-1-对甲苯基-1H-吡唑-4-基亚甲基)-苯1,2-二胺(H(2)L(3))和N,N-双-( 3,5-二甲基-1-对磺酰基-1H-吡唑-4-基亚甲基)-苯1,2-二胺(H(2)L(4))是由5-氧代-3-甲基-1-对甲苯基-1H-吡唑-4-甲醛或4-(4-甲酰基-5-氧代-3-甲基-吡唑-1-基)-苯磺酸和邻苯二胺或乙二胺。并通过元素分析,FT-IR,(1)H NMR和GC-MS对其进行表征。通过[Mn(3)(mu(3)-O)(OAc)(6)(H(2)O)(3)]。3H(2)的缩合制备相应的Mn(III)席夫碱配合物带配体H
