Molecular Architectures Derived from Metal Ions and the Flexible 3,3′-Bipyridine Ligand: Unexpected Dimer with Hg(II)

The flexible ditopic ligand 3,3-bipyridine (3,3-bpy) has been reacted with a series of transition metal species (Ag+, Hg2+, cis-a2M2+ (a=NH3 or a2=en; M=Pt,Pd), trans-a2Pt2+ (a=NH3)) in an attempt to produce discrete cyclic constructs. While Ag+ gave a polymeric structure {[Ag(3,3-bpy)](ClO4) ⋅ H...
