3D copper coordination polymers based on N-heterocyclic ligands with different topology

Two novel three-dimensional (3D) coordination polymers [Cu3II(mtta)6]n (1) and [Cu2IICu3I(trz)4Br3]n·nH2O (2) (mtta = 5-methyltetrazolate, trz = 1,2,4-triazole) were synthesized and structurally characterized. Complex 1 shows a 3D porous metal–organic framework. By the topology analysis, the complicated architecture of 1 can be simplified to be the 4-connected diamond-type net. Compound 2 is a two-fold interpenetrating 3,5-connected 3D framework with new topology.
