| Abstract: | Reactions of Co(ClO4)2·6H2O, Cu(NO3)2·3H2O with 4,4′‐dipyridylsulfide (dps) give rise to coordination polymers {Co(dps)2(DMF)2]·2(ClO4)·2dps}n ( 1 ) and {Cu(dps)2(DMF)(H2O)]·(PF6)·(NO3)}n ( 2 ) (DMF = formydimethylamine), respectively. X‐ray diffraction analyses reveal that compound 1 has a one dimensional (1D) chain structure, whereas compound 2 is built of the non‐interpenetrating wave‐like (4, 4) nets. Close inspection of the abundant charge‐assisted weak hydrogen bonds (C‐H···X, X = O, F) between the anions and frameworks in these compounds reveals that the appearance of anion may have a subtle effect on the framework topology. Furthermore, quite few examples of framework holding two different anions only via weak effects as 2 were observed in coordination polymers. |
