摘要
The title ligand (L(-)) forms a 1:1 complex [TIL] in which the Tl-I ion lies within the hexadentate cavity, coordinated strongly by the pyrazolyl N atoms but only very weakly by the pyridyl N atoms; in contrast the 3:2 complex [Ag(3)L(2)][ClO4] contains a triangular {Ag-3}(3)+ cluster core within the cavity of each ligand which accommodates the larger guest by increasing the apical N-B-N angles.
