Two new metal complexes [Zn( L 1 )] n ( 1 ) and [Cd 3 ( L 2 ) 2 Cl 2 (H2O)6] n ( 2 ) (H 2 L 1 = 1,5‐bis(tetrazol‐5‐yl)‐3‐oxapentane, H 2 L 2 = bis(tetrazol‐5‐yl)methane) have been synthesized and characterized by elemental analysis, IR spectroscopy and single‐crystal X‐ray diffraction analysis. Complex 1 was a 2‐D sheet constructed by L 1 and Zn(II) center, further assembled to form a three‐dimensional (3‐D) supramolecular networks through weak hydrogen‐bonding interactions. In the complex 2 , there were two unequivalent Cd(II) centers, and some of ligands L 2 adopted chelate coordination mode, and others adopted bridge coordination mode linking the Cd1 center and simultaneously bridging the Cd2 center, the Cl ‐ anions adopted μ 2 bridging mode, ligands L 2 and the Cl ‐ anions linked the Cd(II) centers to form a 3‐D supramolecular networks.
