摘要
A new transition-lanthanide metal-organic framework coordination complex, namely [Ag2Dy(nic)4(H2O)4 center dot ClO4 center dot H2O]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.
