Solvothermal reactions of CuX2 (X = NO3, Cl, Br, I) with tetra-pyridyl-functionalized calix[4]arene afforded four novel coordination polymers. Complexes 1−4 are characterized by infrared spectroscopy, thermogravimetric analysis, single-crystal X-ray diffraction, and powder X-ray diffraction. Complex 3 showed the best catalytic properties for the synthesis of versatile propargylamines from the A3 reaction of formaldehyde with a variety of alkynes and amines.
