Porous Chiral Metal Organic Carboxylate Frameworks with a Double-interwoven SrSi2 Topology: M3(TTCA)2·6DMF·7H2O (TTCA = triphenylenetricarboxylate; M = Zn2+, Cd2+)
We have succeeded in assembling a new trigonal aryne ligand, triphenylene-2,6,10-tricarboxylic acid (H 3 TTCA) with metal ions to give M 3 (TTCA) 2 ·6DMF·7H 2 O (M = Zn 2+ and Cd 2+ ) (DMF = N,N-dimethylformamide), which networks show non-interpenetrated porous metal carboxylate frameworks and belong to a novel doubly-interwoven SrSi 2 topology.
