Synthesis and crystal structure of the novel transition- metal substituted tin hydride H2Sn2[Mn(CO)5]4

Abstract

Dicyclopentadienyltin reacts with manganese pentacarbonyl hydride to give the first transition-metal substituted ditin dihydride, H[Mn(CO)5]2Sn---Sn- [Mn(CO)5]2H, the structure of which has been determined by X-ray analysis.

The compound crystallizes in the monoclinic space group with four molecules in a unit cell of DIMENSIONS = a = 15.71, b = 17.18, c = 12.51 Å and β = 107.3°.

Reaction of the dihydride with CCl4 and CBr4 gives Cl2Sn2[Mn(CO)5]4 and Br2Sn2[Mn(CO)5]4, respectively. With acrylonitrile the hydrostannationn product is formed.
