A 2D brickwall architecture from a double-T-shaped ligand and hybrid coordinatively unsaturated copper: Synthesis, structure, and framework dynamic

A double-T-shaped ligand (H4BPTC) as the spacer has been first used to direct the assembly of a 2D coordination polymer with brickwall network topology, [Cu2(BPTC)(Im)4(H2O)(DMF)]n (1) (DMF = N,N-dimethylformamide, H4BPTC = Biphenyl-3,3′,4,4′-tetracarboxylic acid, Im = imidazole), which exhibits an interesting framework dynamic upon de-/resolvation.
