Heteropolymetallic aggregates from [Pd2(dppf)2(µ-S)2]. Bonding and structural analysis of [Ag2Pd2Cl2(dppf)2(µ3-S)2]·4CH2Cl2[dppf = Fe(C5H4PPh2)2]—a flat {Pd2S2} core with two AgCl ‘tails’

Abstract

Nucleophilic addition of the heterometallic complex [Pd₂(dppf)₂(µ-S)₂][dppf = 1,1′-bis(diphenylphosphino)-ferrocene] to [AgCl(PPh₃)] or AgCl gave [Ag₂Pd₂Cl₂(dppf)₂-(µ₃-S)₂], the first example of a heteropolymetallic aggregate based on a {Pd₂S₂} core and whose crystal structure shows a planar {Pd₂S₂} ring with two protruding AgCl fragments.
