The reaction of the asymmetric 4-(aminomethyl)
pyridine (4-am
p) ligand with silver(I) salts of trifluoromethanesulfonate(triflate, OTf
-), trifluoroacetate (tfa
-), or tetrafluoroborate (BF
4-) have
produced a variety of one- and two-dimensionalstructural motifs de
pending u
pon the ratio in which the com
ponents are mixed. When the
pro
portion of ligand tometal is 1:1, linear coordination
polymers are formed with silver(I) OTf
- (
1) and tfa
- (
2). Altering the ratio to 2:1,a linear
polymer of corner-shared boxes (
3) is formed with tfa
-, a linear box-in-box "chain link"
polymer (
4) isformed with OTf
-, and a two-dimensional sheet (
5) is constructed with BF
4-. Addition of 5,5'-dimethyl-2,2'-bi
