Octahedral and trigonal prismatic structure preferences in a bicyclic hexaamine cage for zinc(II), cadmium(II) and mercury(II) ions

Bygott, Alexia; Geue, Rodney; Ralph, Stephen; Sargeson, Alan; Willis, Anthony


The synthesis and characterisation of complexes of the hexaamine cage ligand facial-1,5,9,13,20-pentamethyl-3,7,11,15,18,22-hexaazabicyclo[7.7.7] tricosane (fac-(Me)5-D3 htricosaneN6) with Zn(ii), Cd(ii) and Hg(ii) is reported. Single crystal X-ray structural analyses of the Cd(ii) and Hg(ii) complexes reveal that the coordination spheres of both cations have an unusual trigonal prismatic stereochemistry organised by the ligand substituents and cavity size. This is unprecedented for hexaamine...[Show more]
