Heteropolymetallic aggregates from [Pd 2 (dppf) 2 (µ-S) 2 ]. Bonding and structural analysis of [Ag 2 Pd 2 Cl 2 (dppf) 2 (µ 3 -S) 2 ]·4CH 2 Cl 2 [dppf = Fe(C 5 H 4 PPh 2 ) 2 ]—a flat {Pd 2 S 2 } core with two AgCl ‘tails’

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.
