The reactions of the hydroxo complexes [M2R4(
-OH)2]2- (M = Pd, R = C6F5, C6Cl5; M = Pt, R = C6F5),[{PdR(PPh3)(-OH)}2] (R = C6F5, C6Cl5), and [{Pt(C6F5)2}2(-OH)(-pz)]2- (pz = pyrazolate) with H2S yieldthe corresponding hydrosulfido complexes [M2(C6F5)4(-SH)2]2-, [{PdR(PPh3)(-SH)}2], and [{Pt(C6F5)2}2(-SH)(-pz)]2-, respectively. The monomeric hydrosulfido complexes [M(C6F5)2(SH)(PPh3)]- (M = Pd, Pt) havebeen prepared by reactions of the corresponding binuclear hydrosulfido complexes [M2(C6F5)4(-SH)2]2- withPPh3 in the molar ratio 1:2, and they can be used as metalloligands toward Ag(PPh3)+ to form the heterodinuclearcomplex [(C6F5)2(PPh3){S(H)AgPPh3}], and toward Au(PPh3)+ yielding the heterotrinuclear complexes [M(C6F5)2(PPh3){S(AuPPh3)2}]. The crystal structures of [NBu4]2[{Pt(C6F5)2(-SH)}2], [Pt(C6F5)2(PPh3){S(H)AgPPh3}],and [Pt(C6F5)2(PPh3){S(AuPPh3)2}] have been established by X-ray diffraction and show no short metal-metalinteractions between the metallic centers.
