Abstract

The interplay of argentophilic and dipolar (π-acid···base) interactions, on one hand, and the presence or absence of interstitial solvent molecules, on the other, determines the supramolecular organization of trinuclear silver-pyrazolato complexes in the solid state. The crystal structures of one gold and six silver metallacyclic complexes of the type [M I (μ-pz*)] 3 , where pz* are the substituted pyrazolato anions 3,5-Ph 2 -pz, 3-Me-5-Ph-pz, 4-Br-3,5-Ph 2 -pz, 4-Br-3- t Bu-pz and ...
