Partially Ordered Lanthanide Carboxylates with a Highly Adaptable 1D Polymeric Structure.

ABSTRACT: A new family of 14 isostructural [Ln(piv)₃(en)]_∞ lanthanide pivalate (piv^-, 2,2-dimethylpropanoate) complexes with ethylenediamine (en) was synthesized by a topology-preserving transformation from 1D coordination polymers [Ln(piv)₃]_∞. The crystal structures of the compounds were determined by single-crystal and powder X-ray diffraction, which demonstrated that despite the regular ligand arrangement within the chains, the latter are intricately packed within the partially ordered crystal, as only two of four ligands are strictly bound by the translational symmetry. The peculiarities of the lanthanide coordination environment were explored by total X-ray scattering with pair distribution function analysis. Periodic DFT calculations revea
