The titanium(IV) complexes of the unsymmetrical Schiff base ligands (L) of ethylenediamine and salicylaldehyde, o‐hydroxyacetophenone, o‐hydroxynapthaldehyde have been prepared and characterized when unsymmetrical ligands are synthesized through in situ partial displacement of the symmetrical bis‐Schiff bases. Compounds have been characterized by elemental analysis, electronic, (Infra‐red) IR, 1H NMR
乙二胺和水杨醛,邻羟基苯乙酮,邻羟基萘乙醛的不对称Schiff碱配体(L)的钛(IV)配合物已经制备并表征了通过对称双Schiff碱的原位部分取代合成不对称配体的特征。已通过元素分析,电子(红外),1H NMR光谱数据,磁化率测量和摩尔电导对化合物进行了表征,并提出了八种配合物的配合几何形状。已发现该复合物具有1:2:1(M:L:B)的化学计量比(B是二级配体)。在体外检查了制备的复合物对细菌和真菌生长的生物功效,以评估其抗微生物潜力。
