Synthesis and characterization of [small beta]-triketimine cobalt complexes and their behaviour in the polymerization of 1,3-butadiene

Dalton Transactions - 16 September, 2014 - 12:17

Dalton Trans., 2014, Advance Article
DOI: 10.1039/C4DT02196G, PaperMohammed N. Alnajrani, Francis S. Mair
Cobalt II ions ligated by fac-[small kappa]3-[small beta]-triketimine ligands form bromide-bridged square-based pyramidal dimers which upon activation with MAO and fed with a constant supply of butadiene produce high-cis-1,4-polybutadiene with activities and molecular weights surpassing all previously seen for this metal.

The new isostructural oxohalides [Sb4O7+3[small delta]X4][Zn3]1+[small delta] (X = Cl, Br, I), [small delta] [approximate] 0.2 have a composite structure, in which the Zn atoms are best described in a second-unit cell. The composite nature of the structure leads to a charge imbalance that is compensated by oxygen vacancies.
