A methanol solution of 4,4′‐bipyridine reacts with Cu 2 A 4 (H 2 O) 2 to yield coordination polymers of general formula: [Cu 2 A 4 (bipy)] n [A: CH 2 C(Me)CO 2 − (1), CH 2 CHCO 2 − ( 2 ); bipy: 4,4′‐bipyridine]. They were characterized by elemental analyses, IR spectra and thermal analyses. The X‐ray structure analyses of 1 show a one‐dimensional chain structure where the binuclear structural units Cu 2 [CH 2 C(Me)CO 2 ] 4 are bridged by 4,4′‐bipyridine molecules. Furthermore, the binuclear units between adjacent layers can form micropores. The temperature‐dependent magnetic susceptibility of 1 indicates that the strong antiferromagnetic interaction exists between copper(II) atoms in the binuclear units.
