The complexes of ML2 were synthesized where M= Co(II), Ni(II) and Cu(II) and L= 2-Butyl thioquinazoline 4 (3H)- semicarbazone (BTQS). The ligand have been synthesized by condensation of thioquinazoline-4(3H)-one with semicarbazide hydrochlande characterized by molar mass, elemental analysis, Infrared spectra, electronic spectra, magnetic susceptibility and molar conductance measurements .The ligand BTQS acts as neutral bidentate chelating agent and coordinated to metal ions through azomethine nitrogen and carbonyl oxygen of semicarbazone moiety. The remaining Coordination centres are satisfied by anions such as Cl-, Br-, I- and NO3-.
合成了 ML2 的配合物,其中 M= Co(II)、Ni(II) 和 Cu(II),L= 2-丁基硫代喹唑啉-4(3H)-半咔唑酮 (BTQS)。配体是由硫代喹唑啉-4(3H)-酮与半咔嗪氢烷基缩合合成的,通过摩尔质量、元素分析、红外光谱、电子光谱、磁感应强度和摩尔电导测量对其进行了表征。配体 BTQS 作为中性双齿螯合剂,通过半咔嗪酮分子中的偶氮甲基氮和羰基氧与金属离子配位。其余的配位中心由 Cl-、Br-、I- 和 NO3- 等阴离子提供。
