translate English to French: The complexes (L—L)M(pz)2 {(L—L) = (Ph2PCH2)2, M = Pt, Pd; (L—L) = 2,2′-dipyridine, M = Pt} and (L—L)M(pz′)2 {(L—L = (Ph2PCH2)2, M = Pt; (L—L) = 2,2′-dipyridine, M = Pt, Pd} where pzH = pyrazole and pz′H = 3,5-dimethylpyrazole, behave as ligands towards suitable acceptors affording 1:1 or 1:2 adducts.
Les composés (L—L)M(pz)2 {(L—L) = (Ph2PCH2)2, M = Pt, Pd; (L—L) = 2,2′-dipyridine, M = Pt} et (L—L)M(pz′)2 {(L—L) = (Ph2PCH2)2, M = Pt; (L—L) = 2,2′-dipyridine, M = Pt, Pd} où pzH = pyrazole et pz′H = 3,5-diméthylpyrazole, peuvent complexer sur des accepteurs convenables en conduisant à des composés d'addition 1:1 ou 1:2.
