Abstract

Abstract: The present paper covers the reaction of sodium tricarbonyl cyclopentadienyl or substituted cyclopentadienyl tungsten with triphenyl(tribenzyl) tin chloride or diphenyl(dibenzyl) tin dichloride to yield bimetallic complexes R₃SnW(CO)₃Cp^* or trimetallic complexes R₂Sn[W(CO)₃Cp^*]₂(R=Ph, PhCH₂; Cp^*=C₅H₅, CH₃C₅H₄, CH₃COC₅H₄, 1,2,4-Ph₃C₅H₂). They were characterized by means of elemental analysis, IR and ¹H NMR. The crystal of Ph₃SnW(CO)₃C₅H₄CH₃ is orthorhombic, space group is P_bca with a =1.146 5(2) nm, b =1.674 7(6) nm, c =2.496(1) nm, Z =8 and Sn—W bond length of 0.283 22 nm.

Key words: Bimetallic, Trimetallic, Metal-metal-bond
