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 (4·62)2(4·67·82)2(65·10) net for [Cd2(AmTAZ)2(AzTAZ)]n (1) and a 4-connected (62·84)(64·82)(65·8)2 net for [Cd(AzTAZ)2(H2O)]n (2), whereas AmTAZ retains its original form in a heterometallic complex, [Ag2Cd(AmTAZ)4]n (3).
