Poly borate complexes, group

Properties of nickel poly(pyrazol-l-yl)borate complexes such as solubility, coordination geometry, etc., can be controlled by appropriate substituent groups on the pyrazol rings, in particular in the 3- and 5-positions. Typical complexes are those of octahedral C symmetry (192)°02-604 and tetrahedral species (193). In the former case, two different tris(pyrazolyl)borate ligands may be involved to give heteroleptic compounds.602,603 Substituents in the 5-position mainly provide protection of the BH group. Only few representative examples are discussed here. [Pg.300]

It is perhaps unsurprising that the role of phosphane ligands in group 10 poly(pyrazolyl)borate complexes can often be summarized as "spectator-ial," and in many instances is incidental in respect of chemistry. Indeed, the dominant utility of these ligands is as donors with which to trap or stabilize coordinately unsaturated materials. [Pg.186]
