A New “Opened-Cube” (H₂O)₁₀ Cluster and Undulated Water Chain in Porous Metal−Organic Frameworks

Abstract

A novel three-dimensional coordination polymer [Cd2(btec)(btb)3](H2O)10 (1) (btb = 1,4-bis(1,2,4-triazol-1-yl)butane; btec = 1,2,4,5-benzenetetracarboxylate) containing an “opened-cube” with an outer edge discrete water decamer and a thick two-dimensional network [Cd2(phth)2(btb)(H2O)3](H2O)4.5 (2) (phth = 1,2-benzenedicarboxylate) containing an undulated water chain have been synthesized and characterized by single crystal X-ray diffraction analysis.
