The novel Schiff-base 2,5-pyrrolediylbis[N-(o-hydroxyphenylaldimine)] (SBH2) has been synthesized by the condensation of 2,5-pyrroledicarboxaldehyde and o-amino-phenol. The reactions of the Schiff-base with several transition- and post-transition-metal ions have been investigated. The Schiff-base reacts as a tetradentate dianion without deprotonation of the pyrrole. The complexes M(SB)·nH2O have been
通过2,5-吡咯二甲醛和邻氨基苯酚的缩合反应合成了新型的席夫碱2,5-吡咯二基双[ N-(邻羟基苯二胺)](SBH 2)。研究了席夫碱与几种过渡金属和过渡金属离子的反应。席夫碱以四齿二价阴离子形式反应,而吡咯没有去质子化。已分离出配合物M(SB)· n H 2 O,并用n= 1、2或3表征。SB是席夫碱的阴离子。M =二价Mn,Co,Ni,Cu,Zn,Pd,Cd,Pb或UO 2。M = Cu,X = NO 3的双核络合物M(SB)MX 2,并且M = Ni或Pd,X = Cl,也已被隔离。
