Bonding interaction between Group 10 and 11 metals. Synthesis, structure and properties of [M3(S2CNR2)6M′2]2+(M = Pt or Pd; M′= Ag or Cu; R = Et, Pri, Prn, Bunor C6H11)
摘要:
The mixed-metal complexes [M(3)(S(2)CNR(2))(6)M'(2)](2+) (M = Pt or Pd; M' = Ag or Cu; R = Pt, Pr-i, Pr-n, Bu(n) or C6H11 have been prepared quantitatively upon mixing stoichiometric amounts of [M(S(2)CNR(2))(2)] and Ag+ or [Cu(MeCN)(4)](+) in dichloromethane. The structures of nine of them have been determined and are classified into three types: one polymer and two discrete ion structures. Comparison of the structures indicates the existence of a bonding interaction between M and M' that is greater for Pt than Pd and for Ag than Cu. The strong bonding interaction between the Pt and Ag atoms is also supported by the Pt-195-(107,109) Ag coupling constant of 194 Hz for [Pt-3(S(2)CNBu(2)(n))(6)Ag-2](2+).

M′=[AsPh4]+ or [PPh3(CH2Ph)]+) are formed. Reaction of (1; [S–S]–=[S2CNEt2]–) with Na[S2PMe2]·2H2O gives [Pd(S2CNEt2)(S2PMe2)](4a) which partially disproportionates in solution to [Pd(S2CNEt2)2] and [Pd(S2PMe2)2]. Complex (4a) reacts with PPh3 to give [Pd(PPh3)(S2CNEt2)(S2PMe2)](5a) which possesses bidentate [S2CNEt2]– and unidentate [S2PMe2]– groups. In contrast, reaction of [Pt(C8H12)Cl2] and Na[S2CNEt2]·3H2O
