Hydrothermal preparation of novel Cd(II) coordination polymers employing 5-(4-pyridyl)tetrazolate as a bridging ligand.

The reaction of 4-cyanopyridine with NaN(3) in the presence of H(2)O and a Lewis acid (CdCl(2)) affords a novel 3D pillared-layered fluorescent and phosphorescent coordination polymer Cd(3)(OH)(2)Cl(2)(4-PTZ)(2) (4-PTZ = 5-(4-pyridyl)tetrazolate) (1) while the direct reaction of CdCl(2) with H-PTZ gives the simpler species Cd(4-PTZ)(2)(H(2)O)(2). The solid-state structure and nature of 1 provide an indication of the type of materials that may be formed as intermediates in the Sharpless-Demko reaction for the generation of 5-substituted 1H-tetrazoles.
