Abstract : The present study was based on the assumption that a neutral Boron Pyrazole species would likely exist in a polymeric structure. Therefore, it should contain the bridging Boron Pyrazole units typical for pyrazaboles but also terminal B bonded Pyrazole groups and thus would be related to B-poly(1-pyrazolyl)pyrazaboles. Furthermore, a (pz)3B-B(pz)3 ion should be similar to a RB(pz)3 ion but for the fact that the former has two polydentate sites. These possibilities should provide for interesting variations as compared to the chemistry of B-(1-pyrazolyl)pyrazaboles and poly(1-pyrazolyl)borates, respectively. Keywords: tetrakis(1-pyrazolyl)dibor ane(4), (monomer, oligomers), bis(pyrazole)-tetrakis(1-pyrazolyl)diborane(4), hexakis(1-pyrazolyl)diborane(4) ate complexes.
