title: New insights into the aggregation of silver pyrazolides using sterically hindered bidentate pyrazole ligands.
abstract: Recrystallisation of Ag[L(1)] (HL(1) = 3{5}-[pyrid-2-yl]-5{3}-tert-butylpyrazole) in the presence of halide anions leads to two polymorphs of [Ag(3)(μ-Br)(μ-L(1))(2)], which differ in their mode of supramolecular association, and the cluster [Ag(10)(μ-L(1))(8)]Cl(2). In contrast, Ag[L(2)] (HL(2) = 3{5}-[isoquinol-1-yl]-5{3}-tert-butyl-pyrazole) crystallises as a cyclic tetrameric molecule.
