Organometallic dithiolene complexes of benzenedithiolate analogues with π-coordinating and π-interacting Cp* ligand

Sulfur-rich CpCo(dithiolene) complexes: Isostructural or non-isostructural couples of CpCo(III) with CpNi(III) dithiolene complexes

“…In addition, there are intermolecular face-to-face stacks between the dmid ligands, and these intermolecular interactions lie on 1D column along the c axis in the crystal, with a pseudo-4-fold-symmetry arrangement. The similar arrangement has been reported in the [Cp*Co(dcdmp)] (dcdmp ¼ 2,3-dicyano-5,6-dimercaptopyrazine) [30]. In the crystal of [CpNi(dmid)] , the molecular stack is 1D, but different from [CpCo(dmid)] because of the non-isostructure [23b].…”

“…synthesized the title palladium dithiolene complex, (I), derived from 2,3-dicyano-5,6-dimercaptopyrazine ligand (Tomura et al, 1994). The ligand is expected to extend the π-conjugation of the complex resulting in decreased Coulombic repulsion (Belo et al, 1999(Belo et al, , 2004Nomura et al, 2009;Rabaça & Almeida, 2010 (Yamashita & Tomura, 1998). We report here the molecular and crystal structures of (I).…”

“…Metal dithiolene complexes have been widely investigated as conducting, magnetic or nonlinear optical materials (Cassoux et al, 1991;Robertson & Cronin, 2002). Dithiolene ligands including the 2,3-dicyano-5,6-dimercaptopyrazine (dcdmp) moiety have extended -conjugated systems and are expected to coordinate to transition metals, constructing organometallic coordination polymers (Nomura et al, 2009;Rabaça & Almeida, 2010). In addition, intermolecular SÁ Á ÁN and SÁ Á ÁS contacts involving peripheral S and N atoms of these ligands may lead to the formation of unique molecular networks (Yamashita & Tomura, 1998).…”
