Two Novel Three-dimensional Networks Constructed by Mn or Cd Ion and Tartrate: Syntheses, Structures and Properties

AbstractTwo coordination polymers with the same ligand but different metal ion [Cd(C 4 H 4 O 6 )] n (1) and [Mn 2 (C 4 H 4 O 6 ) 2 (H 2 O)] n (2) (C 4 H 4 O 6 = tartrate dianion) have been synthesized. Compound 1 exhibits novel (4, 4)-connected 3-D network with (4.6.8 4 ) 4 (4.6 2 .8 2 .10)(4.6 2 .8 3 )(4.6 3 .8 2 ) 4 (4.8 5 ) 2 topology, Cd centers are connected by η 6 , μ 4 -mode tartrate ligands. For compound 2, Mn centers are link by η 6 , μ 4 -mode and η 5 , μ 3 -mode tartrate ligands to form (4, 3)-connected 3-D network with (4.8 2 )(4.8 4 .10) topology. Additionally, 1 displays an intense luminescent emission and 2 displays weak antiferromagnetic coupling.Graphical AbstractTwo coordination polymers with the same ligand but different metal ion [Cd(C 4 H 4 O 6 )] n (1) and [Mn 2 (C 4 H 4 O 6 ) 2 (H 2 O)] n (2) (C 4 H 4 O 6 = tartrate dianion) have been synthesized.
