Heteropolymetallic aggregates from [Pd2(dppf)2(μ-S)2]. Bonding and structural analysis of [Ag2Pd2Cl2(dppf)2(μ 3-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-(μ 3-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.
