Abstract Five novel nickel(II) complexes of disubstituted diphenyldithiophosphates, [(ArO) 2 PS 2 } 2 Ni] [Ar = 2,4-(CH 3 ) 2 C 6 H 3 ( 1 ), 2,5-(CH 3 ) 2 C 6 H 3 ( 2 ), 3,4-(CH 3 ) 2 C 6 H 3 ( 3 ), 3,5-(CH 3 ) 2 C 6 H 3 ( 4 ) and 4-Cl-3-CH 3 C 6 H 3 ( 5 )], have been synthesized in aqueous medium and structurally characterized by IR, heteronuclear NMR ( 1 H, 13 C and 31 P) spectroscopic and single
摘要五种新颖的二取代二苯基二硫代磷酸镍[((ArO)2 PS 2} 2 Ni] [Ar = 2,4-(CH 3)2 C 6 H 3(1),2,5-(CH)配合物3)2 C 6 H 3(2),3,4-(CH 3)2 C 6 H 3(3),3,5-(CH 3)2 C 6 H 3(4)和4-Cl-3 -CH 3 C 6 H 3(5)]已在水性介质中合成,并通过IR,异核NMR(1 H,13 C和31 P)光谱和单晶X射线分析对其结构进行了表征。配合物1和5在三斜空间群P 1中结晶,而配合物4在单斜空间群P 2 1 / n中结晶。在这些络合物中,配体通过两个硫醇盐硫原子作为二齿螯合剂与镍离子配位,形成螺环系统。配合物的晶体结构测定1,图4和图5揭示了配合物由单核单元组成,其中镍(II)离子以扭曲的正方形平面配位环境以双齿形式配位。循环伏安法实验被用来探测复合物4的氧化还原能力。已对所研究的复合物以
