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

H. V. R. Dias and J. Thankamani

Synopsis: [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.

Formula: [Tl(C10H4BF12N4)] and [Tl(C15H4BF18N6)]
