New bis- and trispyrazolylborate (scorpionate) ligands derived from 3-(2,4-
dimethoxyphenyl)pyrazole have been synthesized. They can function as N,O-po
lydentate donors, as was demonstrated in the structure of the octahedral co
mplex Ni[Bp((2,4(OMe)2Ph))](2). The structure of Tl[Tp((2,4(OMe)2Ph))] has
also been determined.
