Imposing high-symmetry and tuneable geometry on lanthanide centres with chelating Pt and Pd metalloligands.

ABSTRACT: Exploitation of HSAB preferences allows for high-yield, one-pot syntheses of lanthanide complexes chelated by two Pd or Pt metalloligands, [M^II(SAc)₄]^2- (SAc^- = thioacetate, M = Pd, Pt). The resulting complexes with 8 oxygen donors surrounding the lanthanides can be isolated in crystallographically tetragonal environments as either [NEt₄]⁺ (space group: P4/mcc) or [PPh₄]⁺ (space group: P4/n) salts. In the case of M = Pt, the complete series of lanthanide complexes has been structurally characterized as the [NEt₄]⁺ salts (except for Ln = Pm), while the [PPh₄]⁺ salts have been structurally characterized for Ln = Gd-Er, Y. For M = Pd,
