Abstract
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)2THF with (Ph 4As)+(SnCl3)- gave the ionic complex [Ph4As]+[CpMn(CO)2SnCl3] - (I). The action of C6F5MgBr on the complex C5H5Mn(CO)(NO)SnCl3 produced C 5H5Mn(CO)(NO)Sn(C6F5)3 (II). Replacement of the Cl ions in the complex [CpFe(CO)2] 2SnCl2 by phenylacetylenide groups gave rise to the neutral complex [CpFe(CO)2]2Sn(C≡CPh)2 (III). A reaction of (Dppm)PtCl2 (Dppm is 1,1-bis(diphenylphosphino) methane) with SnCl2 · 2H2O in the presence of diglyme yielded the ionic complex [η3-CH3O(CH 2)2O(CH2)2OCH3)SnCl] +[(η 2-Dppm)Pt(SnCl3)3] - (IV). Transmetalation in a reaction of [(Dppe)2CoCl] [SnCl3] · PhBr (Dppe is 1,2-bis(diphenylphosphino)ethane) with (Dcpd)PtCl2 (Dcpd is dicyclopentadiene) in the presence of SnCl 2 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.
