The azotetrazolate ligand displays a bridging coordination mode, forming an infinite zigzag chain. Intermolecular O¡ªH...O and O¡ªH...N hydrogen bonding and offset face-to-face ¦Ð¨C¦Ð stacking interactions [centroid¨Ccentroid distance = 3.4738 (13) ] lead to a three-dimensional network. %U http://scripts.iucr.org/cgi-bin/paper?S1600536810039632
