hydrochlorides were determined and analyzed. The reaction of the [ReX(CH3CN)2(CO)3]/[ReX(CO)5] (X = Cl and Br) precursors with these ligands yielded different kinds of compounds: the adducts [ReX(HL)(CO)3], in which the ligands were S,N-bidentate; the trinuclear species [Re3Cl2(L23)(HL23)(CO)9]; and the thiosemicarbazonate compounds [Re(L)(CO)3], where the ligand is S,N,Npy-tridentate. Besides, the reaction
已经制备并充分表征了衍生自吡啶-2-甲醛或 1-(2-吡啶基) 乙酮的九种潜在的 S,N,N py-三齿缩氨基硫脲 (HL)。确定并分析了其中六种和两种盐酸盐的 X 射线晶体结构。[ReX(CH 3 CN) 2 (CO) 3 ]/[ReX(CO) 5 ] (X = Cl and Br)前体与这些配体反应生成不同种类的化合物:加合物[ReX(HL)( CO) 3 ],其中配体为S,N-二齿; 三核物质[Re 3 Cl 2 (L 23 )(HL 23 )(CO) 9 ];和氨基硫脲化合物 [Re(L)(CO) 3 ],其中配体是 S,N,N py -三齿。此外,由醛衍生的缩氨基硫脲在甲醇或乙醇中的反应产生了 S,N,N py-三齿半缩醛阳离子 [Re(HL OR )(CO) 3 ]X 和中性 [Re(L OMe )(CO) 3 ]在配位配体将醇基添加到亚胺键后形成络合物。络合物 [ReX(HL)(CO)
