Abstract
Barium and lead(II) complexes of tetraimine Schiff base macrocycles derived from the (2 + 2) condensation of heterocyclic dicarbonyls (2,6-diacetylpyridine and furan-2,5-dicarbaldehyde) and 1,n-diamino-n′-hydroxyalkanes (1,3-diamino-2-hydroxypropane, 1,4-diamino-2-hydroxybutane, and 1,5-diamino-3-hydroxypentane) are reported. The crystal structures of four complexes have been determined.Keywords
