Coordination polymers based on the trinuclear triangular secondary building unit [Cu3(μ3-OH)(μ-pz)3]2+ (pz = pyrazolate) and succinate anion

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(mu(3)-OH)(mu-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.
