Design of Novel Three-Dimensional Coordination Polymers Based on Triangular Trinuclear Copper 1,2,4-Triazolate Units

By controlling the molar ratios of copper dichloride dihydrate and 1,2,4-triazole (trz), we generated a series of novel three-dimensional coordination polymers constructed from μ₃-oxo or μ₃-Cl triangular copper units, exhibiting six-connected porous self-penetrating net, graphite layer, and inorganic−organic hybrid network structures, respectively.
