Forcing Dicyanamide Coordination to f-Elements by Dissolution in Dicyanamide-Based Ionic Liquids.

ABSTRACT: A robust general route to lanthanide dicyanamide (DCA^-) complexes has been developed where f-element salts are dissolved in DCA^--based ionic liquids (ILs) directly or formed in situ, forcing coordination of these normally weakly coordinating soft N-donor anions, even in an ambient, non-moisture-excluding environment. A series of lanthanide complexes [C₂mim][Ln(DCA)₄(H₂O)₄] (C₂mim = 1-ethyl-3-methylimidazolium; Ln = La, Nd, Eu, Tb, Dy, and Yb) and [C₂mim]_3n[La(OH₂)₄(μ²-DCA)₄]_n[La(OH₂)₂(μ³-DCA)₃(μ²-DCA)₄]_2n(Cl)_4n were c
