A number of stannylene complexes with different M: Sn ratios were obtained using various metals and substituents at the tin atom. The structures of the complexes were examined. A reaction of CpMn(CO)(2)THF with (Ph4As)(+)(SnCl3)(-) gave the ionic complex [Ph4As](+)[CpMn(CO)(2)SnCl3](-) (I). The action of C6F5MgBr on the complex C5H5Mn(CO)(NO)SnCl3 produced C5H5Mn(CO)(NO)Sn(C6F5)(3) (II). Replacement of the Cl ions in the complex [CpFe(CO)(2)](2)SnCl2 by phenylacetylenide groups gave rise to the neutral complex [CpFe(CO)(2)](2)Sn(Ca parts per thousand CPh)(2) (III). A reaction of (Dppm)PtCl2 (Dppm is 1,1-bis(diphenylphosphino)methane) with SnCl2 center dot 2H(2)O in the presence of diglyme yielded the ionic complex [eta(3)-CH3O(CH2)(2)O(CH2)(2)OCH3)SnCl](+)[(eta (2)-Dppm)Pt(SnCl3)(3)](-) (IV). Transmetalation in a reaction of [(Dppe)(2)CoCl][SnCl3] center dot PhBr (Dppe is 1,2-bis(diphenylphosphino)ethane) with (Dcpd)PtCl2 (Dcpd is dicyclopentadiene) in the presence of SnCl2 afforded the ionic complex [Pt(Dppe)(2)](3)[Pt(SnCl3)(5)](2) (V). Structures I-V were identified by X-ray diffraction. In these structures, the formally single bonds between the atoms of transition metals M (Mn, Fe, and Pt) and Main Group heavy elements (Sn and P) having vacant d orbitals are appreciably shortened. The M-Sn bond length in complexes II and III are virtually independent of the substituents at the tin atom and the Pt-Sn bond length in complexes IV and V is virtually independent of the Pt: Sn ratio.
