Abstract
The ligands 2,13-dimethyl-3,6,9,12,18-pentaaza-bicyclo[12.3.1]octadeca-1(17),2,12,14(18),15-pentaene (L1) and 2,6-diacetylpyridinebis(semicarbazone) (L2) give pentagonal bipyramidal complexes with some transition metal ions. The structure of [Ni-L2(H2O)2]Cl2·2H2O has been determined by single-crystal X-ray methods. Further reaction of complexes of L1 and L2 with the lithium salt of 7,7′,8,8′,-tetracyanoquinodimethane (tcnq) gives the corresponding adducts.
