Abstract
A new 3-D lanthanide-transition metal coordination polymer [LaCu(PDC)2H2O] n (1) was hydrothermally synthesized from pyridine-3,5-dicarboxylic acid (H2PDC) and characterized by single-crystal X-ray diffraction, IR spectroscopy, and thermal gravimetric analysis (TGA). The microporous framework of 1 can be viewed as constructed by planar binuclear Cu2(PDC)4 building blocks and La(III) chains, a new structural motif in 3d-4f heterometallic coordination polymers. The sample exhibits strong blue emission in the solid state and retains its framework integrity up to ca 380°C.
