Abstract
The synthesis of calix[4](aza)crowns capped by one 'tren' or doubly capped by two azacrowns is described. The crystal structure of the tripodal 'tren' is given. Complexing properties towards Co2+, Ni2+, Zn2+ and Cu2+ are desc ribed. Conclusions are drawn on the role of functional groups and molecular topology in the complexation behavior of calix[4](aza)crowns (C) 2001 Publ ished by Elsevier Science Ltd.
