Stereochemistry of fluoride and mixed-ligand fluoride complexes of zirconium and hafnium

• Structural chemistry of 93 fluoride and 34 mixed-ligand fluoride Zr and Hf complexes are reviewed.
• The structures show systematic variations with the F(L):Zr(Hf) ratio and CN of the metal ion.
• Common coordination polyhedra include octahedron, pentagonal bipyramid and dodecahedron.

As a continuation of the published reviews dedicated to the stereochemistry of fluoride complexes (1998) and mixed-ligand fluoride complexes of zirconium and hafnium (1999), the stereochemistry of 93 fluoride and 34 mixed-ligand fluoride complexes of zirconium and hafnium, whose structures were published since 1998, has been considered. The structure of complex anions (complexes) of structurally studied fluoride and mixed-ligand fluoride complexes of zirconium and hafnium and the dependence of the structural motif of the complex anion (complex) on the F(L):Zr(Hf) ratio in the compound and the central atom coordination number have been discussed. Comprehensive tables containing the chemical formula of the compound, the configuration of the central atom polyhedron reflecting its coordination number, polyhedron composition, the structural motif of the complex, the character of polyhedra association in the structure, and references are presented.
