Abstract
The title ligand (L–) forms a 1:1 complex [TIL] in which the TII 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 [Ag3L2][ClO4] contains a triangular {Ag3}3+ cluster core within the cavity of each ligand which accommodates the larger guest by increasing the apical N–B–N angles.Keywords
