Synthesis, structure and properties of two new 3D frameworks with primitive cubic topology

Two new three-dimensional (3D) coordination polymer [Cu2(tetrazolate)3(OH)]n (1) and [Cd2(tetrazolate)3Br]n (2) were synthesized and structurally characterized. By the topology analysis, the complicated architecture of 1 and 2 are all simplified to be the 6-connected pcu-type net. The variable-temperature magnetic susceptibilities (5–300 K) of 1 shows antiferromagnetic interactions of copper(II) ions bridged tetrazolate ligands and/or hydroxide anion.
