  摘要：

  Synthetic routines for a new ligand C5Me4CH2CH2PMe2 (2b) in forms of its Li- (2b-Li), Na- (2b-Na) salts and in the CH-form (2b-H), as well as for silanes Me3Si-C5H4CH2CH2PMe2 (3a) and Me3Si-C5Me4CH2CH2PMe2 (3b) have been developed. On the basis of it, new half-sandwich [eta(5) :eta(1)-kappa P-C5H4CH2CH2PMe2]ZrCl3 (4a), [eta(5):eta(1)-kappa P-C5Me4CH2CH2PMe2]ZrCl3 (4b) and sandwich [eta(5)-C5Me4CH2CH2PMe2](2)ZrCl2 (5), [eta(5)-C5Me4CH2CH2PMe2][eta(5)-C5Me5]ZrCl3 (6) complexes of Zr(IV) have been prepared and characterized. Along with them, the first example of X-ray structurally characterized dinuclear Zr(IV) complex incorporating both sandwich (6) and half-sandwich (4b) moieties linked one to another by means of Zr P coordination bond 7, has been described. Formation of an analogously organized trinuclear complex 8, built from one sandwich fragment of 5 and two half-sandwich fragments of 4b was proved by NMR spectroscopy methods. Molecular structures of half-sandwich complexes in their solvent-free dimeric forms (4a and 4b) and as 1: 1 adducts with THF (4a-THF and 4b-THF) along with those of dinuclear complex 7 have been established by X-ray diffraction analyses. The dynamic behavior for di- and trinuclear complexes 7 and 8, due to the intermolecular dissociation-coordination of the Me2P-groups in THF-d(8) solutions has been studied by variable-temperature NMR spectroscopy.
