文摘
The crystal structures of two metallo oxides, perrhenate anddichromate, are reported with a diprotonated tetraamido/diamino-based macrocycle, L, in which the floppy ligand assumes a foldedconformation. When the four amides are deprotonated, this sameligand binds transition-metal ions in its tetraanionic form, H-4L.For the divalent metal ions Cu2+ and Ni2+, H-4L again folds anddinuclear complexes are formed. With trivalent metal ions Co3+and Fe3+, the ligand wraps about the metal ions, resulting inmononuclear complexes.
