摘要：

The title ligands bis[(2-pyridyl)methyl]amine (BPA) and bis[(2-benzimidazolyl)methyl]methylamine (BBMA) were used to prepare complexes with zinc salts. 1:1 complexes of BPA with ZnCl2, ZnBr2, ZnI2, Zn(SCN)2, Zn(CH3COO)2, and Zn(NO3)2 as well as of BBMA with ZnCl2, ZnBr2, and Zn(NO3)2 were obtained. Spectroscopic evidence indicates that all these complexes are five-coordinate molecular LZnX2 units. With Zn(ClO4)2, BPA forms a 2:1 complex presumed to be an octahedral ionic L2ZnX2 Species. The crystal structures of BPA . ZnCl2 and BBMA . ZnBr2 reveal distorted square pyramidal resp. trigonal bipyramidal molecular geometries.
