Alkaline earth, lead(II), and cadmium(II) complexes of a nitrogen analogue of [18]annulene; X-ray crystal structure of the lead and cadmium complexes
Abstract
CaII, SrII, BaII, and PbII are effective templates for the synthesis of a conjugated, 18-membered, hexadentate ‘N6’ macrocycle; the crystal and molecular structures of a PbII complex, and of a CdII complex prepared by metal exchange, have been determined.
