摘要：

Tris(pyrazolyl)borate ligands were synthesized by a new route from MeBBr(2) and pyrazole derivatives under very mild conditions at room temperature to give TlL complexes. For L = [MeB(3,5-Me(2)pz)(3)](-) a bridging co-ordination of the ligand is found, interpreted as sterically enforced upon comparison with the structures for L = [MeB(3-Mepz)(3)](-) and [HB(3,5-Me(2)pz)(3)](-).
