(1H-Pyrazole-κN)bis­(tri-tert-but­oxy­silane­thiol­ato-κ²O,S)cadmium

The Cd^II atom in the title complex, [Cd(C₁₂H₂₇O₃SSi)₂(C₃H₄N₂)], is penta-coordinated by two O and two S atoms from the O,S-chelating silane­thiol­ate residue and one pyrazole N atom in a distorted geometry that is slightly closer to trigonal–bipyramidal than to square-based pyramidal. The pyrazole ligand is stabilized within the complex by an intra­molecular N—H...O hydrogen bond. One of the tert-butyl groups is disordered over two orientations with occupancy ratio of 0.534 (6):0.466 (6).

Bromidotetra­kis­(2-ethyl-1H-imidazole-κN³)copper(II) bromide

The Cu^II ion in the title mol­ecular salt, [CuBr(C₅H₈N₂)₄]Br, is coordinated in a square-pyramidal geometry by four N atoms of imidazole ligands and one bromide anion in the apical position. In the crystal, the ions are linked by N—H...Br hydrogen bonds involving both the coordinating and the free bromide species as acceptors. A C—H...Br inter­action is also observed. Overall, a three-dimensional network results.
