New insights into the aggregation of silver pyrazolides using sterically hindered bidentate pyrazole ligands

Abstract

Recrystallisation of Ag[L1] (HL1 = 3{5}-[pyrid-2-yl]-5{3}-tert-butylpyrazole) in the presence of halide anions leads to two polymorphs of [Ag3(μ-Br)(μ-L1)2], which differ in their mode of supramolecular association, and the cluster [Ag10(μ-L1)8]Cl2. In contrast, Ag[L2] (HL2 = 3{5}-[isoquinol-1-yl]-5{3}-tert-butyl-pyrazole) crystallises as a cyclic tetrameric molecule.
