Abstract:
The crystal and molecular structures of a compound of composition W2CSiMe32 CH2SiMe34 have been determined. The compound consists of dinuclear molecules which contain bridging alkylidyne groups, CSiMe3, which, along with the tungsten atoms form planar, rhombic rings, W-C-W-C. Two alkyl groups, CH2SiMe3, are attached to each metal atom to form distorted tetrahedra about the metal atoms. There are two crystallographically independent molecules, each residing on a crystallographic inversion center. The two crystallographically independent W-W distances, 2.5212A, and 2.5492A, are consistent with the presence of W-W single bonds.
