A New Cadmium(II) 2,6-Naphthalene dicarboxylic Acid Three-Dimensional Metal-Organic Frameworks with 6-Connected PCU Topology

摘要

A novel three-dimensional (3D) Cd(II) metal-organic frameworks [Cd3(2,6-ntd)3(DMA)4] (1; 2,6-ntd = 2,6-naphthalene dicarboxylic acid; DMA=N,N-dimethyl acetamide) has been solvothermally synthesized. Single-crystal structure analysis reveals that this compound crystallized in a monoclinic space group of C2/c with a = 14.4124(4) A, b = 18.5328(4) A,c = 21.3181(5) A, α = 90.00°, β = 98.811(2)°, λ = 90.00°, V = 5626.9(2) A~3 and Z = 4. From the viewpoint of topology, it can be reduced to a 6-connected PCU topological network.
