In situ hydrothermal synthesis and structural characterization of two novel CdII–tetrazole coordination polymers

The in situ hydrothermal reactions of 4-nitrobenzonitrile with Cd(ClO4)2 and CdCl2 afforded two novel CdII–tetrazole coordination polymers, 2D network {[Cd(H2O)2(4-nptz)2](H2O)2}n (1) and 1D double chains [Cd(H2O)2(4-nptz)2]n (2). Their synthesis, solid-state structure, and XRPD patterns are reported.
