The complexes 5-C5H5)L2>PF6 have been prepared in high yield from the appropriate complexes and cyclopentadiene in Me2CO in the presence of AgPF6, or with AgNO3 followed by metathesis with NH4PF6.The brighly coloured compounds condudt as uni-univalent electrolytes in Me2CO and CH2Cl2 and have spectroscopic properties consistent with η5 co-ordination of the cyclopentadienyl moiety in solution.The molecular structure of 5-C5H5)(SbPh3)2>PF6*CH2Cl2 has been determined by a single crystal X-ray analysis.The crystals are monoclinic, space group P21/c with a=12.506(6), b=19.002(7), c=18.575(5) Angstoem, β=106.53(3) deg, and Z=4.The structure was solved by heavy-atom methods at 295(1) K and refined by least-squares methods to R=0.051 for 4383 observed reflections.The arrangement of two antimony atoms and the centre of the cyclopentadienyl ring about the palladium atom is approximately trigonal.The co-ordinated cyclopentadienyl moiety shows no significant deviations from planarity.
