New dimetallic palladium and platinum complexes containing the tetrakis(pyrazol‐1‐yl)borate ligand of the type [{(C 6 F 5 ) 2 M} 2 (μ‐pz) 2 B(μ‐pz) 2 ] − (M = Pd, Pt), [{(C 6 F 5 )(L)Pd} 2 (μ‐pz) 2 B(μ‐pz) 2 ] + (L = CN t Bu, NCPh, PR 3 , AsR 3 ) and [{(C 6 F 5 )(Cl)Pd} 2 (μ‐pz) 2 B(μ‐pz) 2 ] − have been prepared using the benzonitrile complexes cis ‐[(C 6 F 5 ) 2 M(NCPh) 2 ] (M = Pd, Pt) or the halide bridged complexes [{(C 6 F 5 )LPd(μ‐X)} 2 ] (L = CN t Bu, NCPh, PR 3 , AsR 3 , tht; X = Cl or Br), and [B(pz) 4 ] − as starting materials. The monometallic [(C 6 F 5 )( t BuNC)Pd(μ‐pz) 2 B(pz) 2 ] and the asymmetric dinuclear [(C 6 F 5 ) 2 Pd(μ‐pz) 2 B(μ‐pz) 2 Pd(η 3 ‐C 4 H 7 )] complexes have also been prepared. The crystal structures of [{(C 6 F 5 ) 2 Pd} 2 (μ‐pz) 2 B(μ‐pz) 2 ] − , [{(C 6 F 5 )( t BuNC)Pd} 2 (μ‐pz) 2 B(μ‐pz) 2 ] + and [(C 6 F 5 ) 2 Pd(μ‐pz) 2 B(μ‐pz) 2 Pd(η 3 ‐C 4 H 7 )] have been established by X‐ray diffraction.
