Crystal structure of polymeric bis-(3-amino-1H-pyrazole)-cadmium dibromide.

ABSTRACT: The reaction of cadmium bromide tetra-hydrate with 3-amino-pyrazole (3-apz) in ethano-lic solution leads to tautomerization of the ligand and the formation of crystals of the title compound, catena-poly[[di-bromido-cadmium(II)]-bis-(μ-3-amino-1H-pyrazole)-κ² N ³:N ²;κ² N ²:N ³], [CdBr₂(C₃H₅N₃)₂]_n or [CdBr₂(3-apz)₂]_n. Its asymmetric unit consists of a half of a Cd²⁺ cation, a bromide anion and a 3-apz mol-ecule. The Cd²⁺ cations are coordinated by two bromide anions and two 3-apz ligands, generating trans-CdN₄Br₂ octa-hedra
