Two mixed-valence copper(I,II) imidazolate coordination polymers: metal-valence tuning approach for new topological structures

A new metal-valence tuning synthetic approach has been utilized to generate two new mixed-valence Cu(I,II) coordination polymers Cu-2(im)(3) and Cu-3(im)(4) (Him = imidazole), which are an unprecedented uninodal 4-connected 4.8(5) topological net and a 4-connected (4,4) net, respectively.
