New class of coordination compounds with noble gas fluorides as ligands to metal ions

A new class of coordination compounds of the type [M n+ (L) p ](AF 6 −) n and [M n+ (L) r ](BF 4 −) n , where M is Mg, Ca, Sr, Ba, Cd, Pb, lanthanides, A is P, As, Sb, Bi and L is XeF 2, XeF 4, XeF 6, KrF 2, was studied. A review of all known coordination compounds with L is XeF 2 is given: (a) synt...

Description
Summary:A new class of coordination compounds of the type [M n+ (L) p ](AF 6 −) n and [M n+ (L) r ](BF 4 −) n , where M is Mg, Ca, Sr, Ba, Cd, Pb, lanthanides, A is P, As, Sb, Bi and L is XeF 2, XeF 4, XeF 6, KrF 2, was studied. A review of all known coordination compounds with L is XeF 2 is given: (a) synthetic routes for the preparation of these compounds; (b) analysis of their crystal structures (molecular, dimer, chain, double chain, layer, strongly interconnected double layers and three-dimensional network); (c) the influence of the ligand XeF 2 (small formula volume, linear, semi-ionic, charge of −0.5 e on each F ligand); (d) the influence of the central metal ion; (e) the influence of the anions: AF 6 − and BF 4 − (the formula volume, Lewis basicity). On the basis of all properties of the metal ions, ligand and anions the obtained variety of the structures is analyzed. ▪
