Abstract
- Two new metal–organic framework namely, [ Ag 3 ( dmpyz ) 1.5 ( btc ) ] n (1), and [ Ag 2 ( dmpyz ) ( pta ) ] n (2), have been synthesized and structurally characterized. Compound 1 is a 3D structure incorporating μ 5 - ( η 1 , η 1 ) : ( η 1 , η 1 ) : ( η 1 , η 1 ) btc and μ 2 - N 1 , N 1 , μ 2 - N 2 , N 3 dmpyz ligands. In compound 2, the μ 5 - η 1 : η 2 : η 3 : η 1 pta and the dmpyz ligands link the [ Ag 4 O 2 ] units into a 2D structure. It is noteworthy that the Ag⋯Ag interactions were observed in the two coordination polymers. The results show that the structural diversity of the polymers is mainly attributed to the usage of diverse ancillary carboxylate ligands. The thermal stabilities and photoluminescence behaviors were addressed.
