A pillar-layered-like metal-organic framework built from dinuclear cobalt chain and a V-shaped bis-pyridyl ligand with different coordination modes

A dinuclear Co based 3D framework has been synthesized by a semi-rigid V-shaped ligand and tripodal multicarboxylate ligand. The OPY ligand adopting two different coordination modes not only expands the dinuclear cobalt chain to a 3D CdSO4-type framework, but also enhance the stability of complex 1.392
