The phosphine chalcogenides Fe[eta-C5H4P(E)Ph2]2 (L) [E = nothing (dppf), S (dptpf) or Se (dpspf)] reacted readily with [Cu(MeCN)4]X (X = BF4, PF6 or ClO4) in CH2Cl2 to give quantitatively the monomeric two-co-ordinated complexes [CuL]BF4 (E = S 1 or Se 2) or polynuclear three-co-ordinated derivatives analysing as [CuL1.5]X (E = S 3 or Se 4), depending on the ligand to copper molar ratio. The complexes have been characterized by multinuclear NMR spectroscopy. Complexes 3 and 4 reversibly dissociate in solution, as was evident from the concentration-and temperature-dependent NMR spectra. The low-temperature 1H, 31P-{1H} and 19F NMR spectra are interpreted in terms of a tetranuclear structure in which each copper atom is trigonally bonded by bridging L ligands and one anion molecule is trapped inside the tetrahedral CuI4 cage. Single-crystal X-ray structure determinations were performed for the two diphosphine chalcogenides and complex 1. The structure of 1 shows a slightly distorted linear two-co-ordination geometry around the copper atom with an S(1)-Cu-S(2) angle of 171.5(2). The Cu-S bond distances [2.144(5) and 2.140(5) A] and the Cu-S-P angles [100.8(2) and 105.5(2)] point towards a substantially sp3 hybridization of the sulfur atoms. In the ferrocene moiety the cyclopentadienyl rings are virtually parallel (dihedral angle between the two planes 6.5) and staggered by 16.1.
