On Zn(ii) 2,2′-bisdipyrrin circular helicates
Coordination of two 2,2′-bisdipyrrin ligands, bearing either methyl ester or methylthioether peripheral groups, with Zn(ii) cations leads not only to the formation of the expected linear helicates but also concomitantly to novel tri- and tetra-nuclear circular species that have been isolated and fully characterized in solution and in the solid state by single-crystal X-ray diffraction.
