The title organic ligands (Hsip) gave, by reaction with d10-metal acetates, complexes of the type M(sip)2 (M = Zn, Cd, Hg), in which the ligand behaved as terdentate, producing a distorted octahedral environment around the metal. The 1H and 13C chemical shifts found for these complexes in DMSO are compared with the corresponding ones of the free ligand. The crystal structure of the zinc derivative
标题有机配体(Hsip)通过与d 10-金属乙酸盐反应,生成M(sip)2型配合物(M = Zn,Cd,Hg),其中配体表现为三齿,产生扭曲的八面体环境金属周围。将在DMSO中发现的这些复合物的1 H和13 C化学位移与相应的游离配体进行了比较。锌衍生物的晶体结构已由衍射仪数据确定,对于1086次独立反射,R = 0.072。晶体是单斜晶体,空间群C 2 / c,其晶胞尺寸a = 18.193(2),b = 24.532(6),c = 11.535(2)Å,β= 103.71(1)°且Z =8。配位反应是通过羰基氧(Zn-O = 2.10,2.16(1)Å),偶氮甲碱氮(Zn-N = 2.04, 2.07(1)Å)和吡啶氮s(Zn-N = 2.24,2.26(1)Å)。
