Abstract

The ligand 1,1′-bis(diphenylthiophosphoryl)ferrocene, dptpf, reacted with various silver complexes to afford two-, three- or four-co-ordinate species. Thus the reaction of dptpf with [Ag(OClO3)(PPh3)] in 1∶1 or 1∶2 molar ratio gave the three-co-ordinate [Ag(dptpf[hair space])(PPh3)]ClO4 or the linear [Ag2(dptpf[hair space])(PPh3)2][ClO4]2 derivatives. Similarly, the treatment of dptpf with AgClO4 in 2∶1 or 1∶1 molar ratio afforded the homoleptic compounds [Ag(dptpf[hair space])2]ClO4 or [Ag(dptpf[hair space])]ClO4; in the latter dptpf acts as a trans-chelating ligand. The complex [Ag(dptpf[hair space])]ClO4 can react further with bidentate ligands such as 2,2′-bipyridine (bipy) or bis(diphenylthiophosphoryl)methane, (SPPh2)2CH2, leading to the four-co-ordinate [Ag(dptpf[hair space])(bipy)]ClO4 or the four-co-ordinate polymeric species [Ag2(µ-dptpf[hair space]){(SPPh2)2CH2}2]n[hair space][ClO4]2n[hair space], which was characterised by X-ray diffraction.
