Coordination Polymers Based on the Trinuclear Triangular Secondary Building Unit [Cu3(μ3-OH)(μ-pz)3]2+ (pz = pyrazolate) and Succinate Anion

This is the authors' abstract. We don't add key points for this paper.

Reaction conditions (solvent, temperature, pressure) and reagents ratios control the formation of different products from the reactions involving Cu II, pyrazole (Hpz), and succinate ion (Suc). Three different coordination polymers (CPs) (one of which porous) based on the trinuclear triangular Cu 3 (μ 3 -OH)(μ-pz) 3 secondary building unit (SBU), as well as a 1D CP based on the Cu(Hpz) 2 SBU were obtained. Moreover, a 3D supramolecular network, formed through quite strong H-bonding interactions involving the mononuclear Cu(HSuc) 2 (Hpz) 4 complex, was also synthesized when an excess of H 2 Suc was added.
