Ag(I)-Mediated In situ Dehydrogenative Coupling of 3-Amino-1,2,4-triazole into 3,3'-Azobis(1,2,4-triazole) in Cd(II) Coordination Polymers
Ag(I)-mediated in situ generation of 3,3'-azobis(1,2,4-triazole) (AzTAZ) from 3-amino-1,2,4-triazole (AmTAZ) through dehydrogenative coupling has been realized during the crystallization process of two Cd(II) coordination polymers with novel topological architectures: a (3, 4, 5)-connected (4 center dot 6(2))(2)(4 center dot 6(7)center dot 8(2))(2)(6(5)center dot 10) 4 net for [Cd-2(AmTAZ)(2)(AzTAZ)](n) (1) and a 4-connected (6(2)center dot 8(4))(6(4)center dot 8(2))(6(5)center dot 8)(2) net for [Cd(AZTAZ)(2)(H2O)](n) (2), whereas AmTAZ retains its original form in a heterometallic complex, [Ag2Cd(AmTAZ)(4)](n) (3).
