The ligand 1,1â²-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 1â¶1 or 1â¶2 molar ratio gave the three-co-ordinate [Ag(dptpf)(PPh3)]ClO4 or the linear [Ag2(dptpf)(PPh3)2][ClO4]2 derivatives. Similarly, the treatment of dptpf with AgClO4 in 2â¶1 or 1â¶1 molar ratio afforded the homoleptic compounds [Ag(dptpf)2]ClO4 or [Ag(dptpf)]ClO4; in the latter dptpf acts as a trans-chelating ligand. The complex [Ag(dptpf)]ClO4 can react further with bidentate ligands such as 2,2â²-bipyridine (bipy) or bis(diphenylthiophosphoryl)methane, (SPPh2)2CH2, leading to the four-co-ordinate [Ag(dptpf)(bipy)]ClO4 or the four-co-ordinate polymeric species [Ag2(µ-dptpf)(SPPh2)2CH2}2]n[ClO4]2n, which was characterised by X-ray diffraction.

二茂铁(dptpf)与各种
银配合物发生反应,生成二配位、三配位或四配位的物质。因此,当 dptpf 与[Ag(OClO3)(PPh3)]以 1¶1 或 1¶2 的摩尔比反应时,会产生三配位的 [Ag(dptpf)(PPh3)]ClO4 或线性的 [Ag2(dptpf)(PPh3)2][ClO4]2 衍
生物。同样,以 2¶1 或 1¶1 的摩尔比将 dptpf 与 AgClO4 处理,可得到同色化合物 [Ag(dptpf)2]ClO4 或 [Ag(dptpf)]ClO4;在后者中,dptpf 起着反式螯合
