Abstract

A variety of network structures have been prepared by transmetalation of a polymer {Na3[Na9(Cbdcp)6(H2O) 18]}n (1) (Cbdcp = N-(4-carboxybenzyl)-(3,5-dicarboxyl) pyridinium) containing dodecahedral Na9 aggregate secondary building units with Cu(II) by modulating the temperature, solvent, and pH. These complexes include a large, zwitterionic hexa-cuprometallocycle [Cu 6(Cbdcp)6(H2O)18] (2) formed in H2O at room temperature, two three-dimensional polymers [Cu 3(Cbdcp)2(OH)2(H2O) 2]n (3) and {[Cu3(Cbdcp)2(OH) 2].2H2O}n (4) isolated from H 2O and DMF/H2O at 135 °C, and a mononuclear complex [Cu(HCbdcp)2(H2O)3].H2O (5) from H2O at 100 °C and pH = 6. All the complexes are robust and water stable. The crystal framework of macrocycle 2 is stable up to 100 °C under vacuum and selectively adsorbs CO2. © 2014 American Chemical Society.
