The reaction of [MCl2(L–L)][M = Pd or Pt, L–L = 1,2-bis(diphenylphosphino)ethane (dppe), 1,2-bis(diphenylarsino)ethane (dpae), 2,2′-bipyridine (bipy), or cyclo-octa-1,5-diene (cod)] with alkali and an azole [pyrazole (Hpz), 3,5-dimethylpyrazole (3,5Me2-Hpz), indazole, or tetrazole] or with a potassium pyrazolate gives the [M(azolate-N)2(L–L)] complexes, where the azolato-ligands are unidentate. While
[MCl 2(L–L)] [M = Pd或Pt,L–L = 1,2-双(二苯基膦基)乙烷(dppe),1,2-双(二苯基ar基)乙烷(dpae),2碱和唑[吡唑(Hpz),3,5-二甲基吡唑(3,5Me 2 -Hpz),吲唑,或四唑]或与吡唑酸钾一起生成[M(azolate- N)2(L–L)]复合物,其中的偶氮配体是未知的。当I 2或HCl裂解金属-氮键时,与HBF 4酸的反应提供单核或双核阳离子,[M(唑)2(L–L)] 2+或[(L–L)M (µ-pyrazolato- NN ')2 M(L–L)]分别为2+;后者的化合物含有杂的吡唑并-配体。
