Synthesis, crystal structure and catalytic property of praseodymium(III) coordination polymer containing tetrazole-5-acetato(tza) anion ligands

A novel 1D coordination compound [Pr2(tza)3(H2O)6]n·4nH2O (1) (tza = tetrazole-5-acetato) was synthesized by the reaction of tetrazole-5-acetic acid with Pr(NO3)3·6H2O in the presence of KOH. This complex showed a specific and good catalytic behavior in the polymerization of styrene. The high molecular weight polymers with narrow molecular weight distributions in good yields were obtained within a few minutes.
