Abstract

The synthesis and characterization of three new tetradentate “bispicen-type” ligands containing a substituted thiophene heterocycle are described [2, 5-thienyl substituents= H (7), Ph (8), or 2-thienyl (9)]. Iron (II) bis (thiocyanate) coordination complexes containing 7-9 were prepared, and the electronic and variable-temperature magnetic properties of complexes containing 7 (10) and 9 (12) are described. Complex 10 features a gradual ...
