A two-fold interpenetrated three-dimensional cobalt(II) complex with dual dicyanamide and 4,4′-bipyridine bridges

A three-dimensional cobalt(II) coordination polymer, Co(4,4'bpy)[N(CN)(2)](2), was constructed using dicyanamide and 4,4'-bipyridine bridges; it consists of two-fold interpenetrated alpha -Po-like networks.
