Pd(ii), Ni(ii), and Cu(ii) complexes of α,α′-ditolylmethanone dipyrroethene

Dipyrroethenes are bipyrrolic ligands with a dianionic bidentate core. The first Pd(ii), Ni(ii) and Cu(ii) complexes of α,α′ ditolylmethanone dipyrroethene were synthesized and their structural and optical properties were discussed.
