Abstract

The new dihydridobis(3-nitro-1,2,4-triazolyl)borate ligand, [H2B(tz(NO2))(2)](-), has been synthesized in dimethylacetamide solution, using 3-nitro-1,2,4-triazole and KBH4 through careful temperature control, and characterized as its potassium salt. The zinc(II) and cadmium(II) complexes, {M[H2B(tZ(NO2))(2)]Cl(H2O)(2)], have been prepared by metathesis of [H2B(tz(NO2))(2)]K with ZnCl2 and CdCl2, respectively. The complexes likely contain a metal core in which the ligand is coordinated to the metal ions in the k(2) -N,N' or k(4)-N,N',O,O' fashion. A single-crystal structural characterization is reported for the potassium dihydrobis(3-nitro-1,2,4-triazolyl)borate. The potassium salt is polymeric and shows several K...N and K...O interactions.
