Thallium(I) complexes of fluorinated bis- and tris(pyrazolyl)borate ligands: [H₂B{3,5-(CF₃)₂pz}₂]Tl and [HB{3,5-(CF₃)₂pz}₃]Tl

[H₂B{3,5-(CF₃)₂pz}₂]Tl has a two coordinate thallium atom with a bent geometry and boat-shaped bis(pyrazolyl)borate ligand. The related tris(pyrazolyl)borate analogue [HB{3,5-(CF₃)₂pz}₃]Tl has a trigonal pyramidal thallium atom.
