Resumen

The isomorphous complexes bis[hydrotris(pyrazolyl)borato]-magnesium(II) chloroform disolvate, [Mg(C₉H₁₀BN₆) ₂]⋯-2CHCl₃, and bis[hydrotris(pyrazolyl)borato] calcium(II) chloroform disolvate, [Ca(C9́H₁₀BN ₆)₂]·2CHCl₃, crystallize in the cubic space group Pa3̄ with Z = 4. The metal atoms occupy sites of 3̄ symmetry, and their coordination is very similar to that found for the unsolvated Mg[HB(Pz)₃]₂ and Ca[HB-(Pz)₃] ₂ complexes (Pz is pyrazole). The inclusion of chloroform molecules on threefold rotation axes not only leads to high-symmetry crystal structures but also plays an important role in stabilizing the three-dimensional supramolecular architecture through facial Pz⋯Cl⋯Pz interactions.
