	abstract = {The reaction of the dilithiodiamidophosphine ligand precursor PhP(CH2SiMe2NPh)(2)Li-2(THF)(2)([NPN]Li-2(THF)(2)) with LnCl(3)(THF)(3) (Ln = Y, Sm, Ho. Yb. Lu; THF = tetrahydrofuran) in refluxing toluene generates the mononuclear complexes [NPN]LnCI(THF) in good yield. The molecular structures have been shown to be five-coordinate in the solid state and in solution. Attempts to prepare alkyl derivatives have only met with partial success; the reaction of MeMgCl with [NPN]YCl(THF) generates the partially characterized mixed-metal derivative [NPN]YMe2MgCl. The reaction with LiAlH4 results in complete ligand exchange and the formation of the tetranuclear lithium aluminum hydride derivative ([NPN]AlH2Li(THF))(2). Reduction of the lutetium derivative with KC8 and naphthalene generated the dinuclear naphthalene-bridged species {[NPN]Lu}(2)(mu-eta (4):eta (4)-C10H8) wherein each Lu centre engages in eta (4)-coordination to opposite sides of the arene moiety. X-ray crystallography was used to characterize the four complexes.},

	abstract = {{The preparation of phosphine complexes of the group 3 elements yttrium and lanthanum and the lanthanide metal lutetium is described. The reaction of 2 equiv of lithium salt of the mixed-donor ligand LiN(SiMe2CH2PR2)2 (R = Me, Ph, Pr(i)) with YCl3 or LuCl3 (R = Me only) leads to the formation of the bis(ligand) complexes MCl[N(SiMe2CH2PR2)2]2. The analogous lanthanum derivative requires the use of the corresponding potassium salt KN(SiMe2CH2PR2)2 (R = Me, Ph) with anhydrous LaCl3 to generate good yields of LaCl(N(SiMe2CH2PR2)2]2. Replacement of the remaining chloride with a hydrocarbyl ligand can be achieved for M = Y and Lu to generate MR[N(SiMe2CH2PMe2)2]2 (M = Y},
