A new 2D coordination polymer material based on 4d-4f heterometallic assembly

摘要

A new transition-lanthanide metal-organic framework coordination complex, namely [Ag_2Dy(nic)_4(H_2O)_4 ClO _4 H_2O]n (nic = nicotinate) (1) has been synthesized by the reaction of the 4d and 4f metal salts with heterocyclic ligand under mild condition and characterized by elemental analysis, IR and single-crystal X-ray diffraction. Compound 1 presents interesting 2D under heterometallic layer generated by the self-assembly of 1D chains of lanthanide-carboxylate with Ag(nic)_2 subunits. Furthermore, the title compound displays an interesting 3D zeolite-like porous topology.
