M. Leirer et al., Synthesis and optical ligand-to-ligand charge transfer of Zn(2, 6-bis(benzimidazolyl)pyridine)-(3,4-toluenedithiolate), J COORD CH, 50(2), 2000, pp. 141-144
The complex Zn[(BzImH)(2)Py](TDT) with (BzImH)(2)Py=2,6-bis(benzimidazolyl]
)pyridine and TDT2-=3,4- toluenedithiolate was prepared and characterized s
pectroscopically. The yellow colour of this compound is caused by an absorp
tion band (lambda(max)=369 nm in ethanol), which is assigned to a ligand-to
-ligand charge transfer transition from TDT2- to the(BzImH)(2)Py ligand.
